Siddharth Singh isn’t your typical tough guy. Sure, he’s India’s first 10-time national Brazilian Jiu-Jitsu champ, a 4-time world medalist, and the guy who earned the country’s first competition BJJ black belt—but talk to him, and you’ll find a regular dude who’s just obsessed with living well. From scrapping in the cage to building Crosstrain Fight Club and coaching India’s first Road to UFC winner, Anshul Jubli, Siddharth’s spent his life figuring out what makes a man strong, inside and out. Now, with 191 Nutrition, he’s bringing that know-how to guys like us—helping us fuel up, recover right, and push harder. For Best for Him, he’s spilling the real stuff: how he balances brutal workouts with business, why he’s taught over 5,000 women to fight back, and what keeps him grounded. Siddharth’s not here to flex—he’s here to show you how to be your best, no BS required.
Your journey from an elite MMA fighter to a wellness entrepreneur is inspiring. How has fitness shaped your personal philosophy on health and well-being?
Fitness is not something I actively think about—it’s just who I am. I don’t wake up wondering whether I should train or not; it’s as natural to me as breathing. It’s ingrained in my daily life, in the way I move, think, and approach challenges. My journey from competing at the highest levels of MMA and BJJ to building Crosstrain Fight Club and launching 191 Nutrition has only reinforced my belief that health isn’t a short-term goal—it’s a way of life. Discipline, resilience, and consistency in training have shaped not just my physical abilities but also my mindset and approach to business. Whether coaching future champions or developing high-performance nutrition, my philosophy remains the same: take care of your body, push your limits, and success will follow.
Well-being isn’t about chasing fitness—it’s about making it a non-negotiable part of who you are.
MMA is both physically and mentally demanding. What are some key wellness practices you follow to maintain peak performance?
For me, performance is an obsession—it’s what drives everything I do, from training world-class fighters to starting 191 Nutrition. Competing at the highest level of MMA and BJJ taught me that training hard isn’t enough; recovery is just as important. I focus heavily on optimizing recovery to maintain peak performance. That means sleeping at least 8 hours every night, ensuring my body has time to repair and recharge. I also take essential supplements like magnesium, zinc, curcumin, glucosamine for joint health, and multivitamins like B12 and D3 to keep my immune system strong and prevent any dips in performance. For active recovery, I mix things up—I run, walk, do yoga, climb, play tennis, and lift weights. These activities keep my body moving without overloading it. And when it comes to nutrition, I prefer eating at home as much as possible, ensuring I fuel my body with clean, high-quality food.This relentless pursuit of performance is exactly why I started 191 Nutrition—to provide athletes and high performers with the best possible fuel to keep pushing their limits.
Many men struggle with consistency in fitness. What advice would you give to someone trying to stay committed to their health goals?
The key to consistency is removing choice from the equation. You don’t ask yourself if you should brush your teeth every morning—you just do it. Fitness should be the same. Make it a fundamental part of your identity, not something you “try to fit in.” Start small but stay consistent. Pick something sustainable—whether it’s lifting, running, BJJ, or even just daily walks. Show up, even on days you don’t feel like it. And focus on long-term progress, not quick fixes. Fitness is a lifelong commitment, not a 30-day challenge. Also, prioritize recovery and nutrition. Train hard, but sleep well, eat clean, and supplement smartly. The more your body feels good, the easier it is to stay consistent. At the end of the day, discipline beats motivation. If you can commit to your health without excuses, results will follow.
As someone who has trained top athletes, what are the most common mistakes men make when it comes to nutrition and supplementation?
One of the biggest mistakes I see men make with nutrition and supplementation is chasing quick fixes instead of focusing on fundamentals. They’ll spend thousands on the latest “super supplement” but ignore basic things like eating real food, sleeping well, and staying hydrated.
Here are some of the most common mistakes:
1. Neglecting foundational supplements – Everyone wants a magic pill, but they ignore essentials like magnesium, zinc, curcumin, glucosamine for joints, and vitamins like B12 and D3. These aren’t flashy, but they’re crucial for long-term health and performance.
2. Eating too much processed food – Men often underestimate how much junk they consume. If you eat out all the time, you have no control over the quality of ingredients. I prefer to eat at home as much as possible to ensure I’m fueling my body properly.
3. Not prioritizing protein – Whether you’re lifting, doing BJJ, or just trying to stay lean, protein intake matters. Most guys don’t eat enough high-quality protein, which slows down recovery and muscle growth.
4. Ignoring gut health – A lot of people don’t realize how important digestion is for performance. If your gut isn’t healthy, you won’t absorb nutrients properly. Prioritizing fiber, probiotics, and anti-inflammatory foods is key.
5. Not hydrating properly – Men focus on food but forget water, electrolytes, and proper hydration, which impacts everything from energy levels to joint health. This obsession with real, performance-driven nutrition is exactly why I started 191Nutrition—to cut through the noise and provide high-quality, effective supplements that actually help athletes perform at their best.
Stress management is a huge part of overall wellness. How do you balance intense training, business, and personal life while staying mentally strong?
The only way to balance intense training, multiple businesses (Crosstrain Fight Club, ADCC India, AJP India, 191 Nutrition), and personal life without burning out is by building strong teams, structures, and systems. I used to think I could do everything myself, but as responsibilities grew, I realized that high performance isn’t about doing more—it’s about doing the right things efficiently. That means:
A. Building a solid team – I surround myself with people I trust—coaches, managers, and business partners—who share my vision and can execute at a high level. I don’t micromanage; I empower them to take ownership.
B. Creating systems that run without me – Every business I run has clear processes, structures, and workflows in place. Whether it’s training athletes, running competitions, or developing nutrition products, everything follows a structured system so it doesn’t rely on me being hands-on 24/7.
C. Prioritizing what matters – I’ve learned to focus on high-impact tasks and delegate the rest. If something isn’t contributing to growth, performance, or well-being, I cut it out.
D. Training is non-negotiable – No matter how busy things get, I never compromise on training. It keeps me mentally sharp and physically ready to perform at my best.
E. Recovery & mental resets – I make time for sleep, active recovery (running, yoga, walking, lifting), and proper nutrition so I can sustain this pace long-term. At the end of the day, stress comes from a lack of structure. If you build the right systems and surround yourself with the right people, you don’t just survive—you thrive. At the end of the day, stress comes from a lack of structure. If you build the right systems and surround yourself with the right people, you don’t just survive—you thrive.
You’ve trained over 5,000 women in self-defense. Why do you think men should also take an active role in promoting women’s safety and empowerment?
Ever since I was a child, I was taught at home that the way you treat a woman says everything about your character. Real men don’t hurt women—they protect, respect, and honor them. This belief was deeply ingrained in me, and it was further reinforced during my time at The Doon School in Dehradun, where values like respect, responsibility, and leadership were an essential part of our upbringing. Having trained over 5,000 women in self-defense, I’ve seen firsthand how empowering them with the right skills transforms their confidence, mindset, and sense of security. But the truth is, women’s safety is not just a women’s issue—it’s a societal issue, and men have a critical role to play in changing things. Men need to take an active role in setting the standard for respect. The way we behave, speak, and interact with women influences the culture around us. If we normalize accountability and respect, we create an environment where mistreatment isn’t tolerated. Strength should never be used to dominate—it should be used to defend. A real man understands that power isn’t about control; it’s about protection. Beyond that, men need to educate and influence the next generation. Young boys need role models who demonstrate how to treat women with dignity. Whether it’s at home, in schools, or in gyms, men must take responsibility for shaping a culture that values respect over aggression. Supporting women’s empowerment isn’t just about teaching them self-defense—it’s about building a world where they feel safe, heard, and valued. That means speaking up when we see disrespect, advocating for equal opportunities, and ensuring that women can thrive without fear. At Crosstrain Fight Club, we don’t just teach women how to fight—we also train men to be better allies. Because true strength isn’t about overpowering others; it’s about standing up for what’s Right.
What are three daily habits you believe every man should incorporate for a healthier and more balanced lifestyle?
If you want a healthier and more balanced life, you don’t need to complicate things. It all comes down to discipline, consistency, and taking care of your mind and body. There are three simple habits that I believe every man should incorporate into his daily routine:
First, move every single day. It doesn’t have to be an intense workout, but your body was built to move. Whether it’s lifting weights, running, walking, playing a sport, or training martial arts, daily movement keeps you strong, energized, and mentally sharp. When you stay physically active, you build resilience—not just in your body, but in your mind. Second, eat clean and treat your food as fuel. Your body is a machine, and what you put into it determines how well it performs. Prioritize whole, nutrient-dense foods and avoid excessive processed junk. Stay hydrated, get enough protein, and take essential supplements like magnesium, zinc, curcumin, glucosamine, and vitamins like B12 and D3 to keep your body functioning at its best. This mindset of fueling for performance is exactly why I started 191 Nutrition—because what you eat directly impacts how you perform, recover, and feel. Third, control your mind before the world does. Every day, take some time to disconnect from distractions—whether through meditation, journaling, reading, or just being in silence. Most men let the outside world dictate how they think and feel, but real strength comes from having control over your own mind. If you move daily, fuel your body properly, and train your mind to stay focused, you’ll have the foundation to perform at your highest level—physically, mentally, and emotionally.
What inspired you to create 191 Nutrition, and how does it specifically cater to men’s fitness and wellness needs?
I created 191 Nutrition because I saw a massive gap in how men approach their nutrition, especially in India. The truth is, the typical Indian diet and modern lifestyle often overlook several essential vitamins and minerals—things like magnesium, zinc, vitamin D3, B12, omega-3s, and even fundamental vitamins like A, B, and C, all of which are crucial for energy, recovery, and overall well-being. As an athlete and coach, I’ve spent years optimizing my own performance through proper nutrition, and I saw firsthand how most men were training hard but neglecting the fuel their bodies actually need. That’s when I knew there had to be a better solution. 191 Nutrition was built to fill these critical gaps—to provide clean, effective, and science-backed supplements that support men’s strength, endurance, and recovery. Vitamins play a massive role in performance and longevity. Vitamin A is essential for vision, immune function, and skin health—yet many don’t get enough of it. Vitamin B-complex (especially B12) is critical for energy production, red blood cell formation, and brain function, something most vegetarians and even non-vegetarians in India are deficient in. Vitamin C is a powerhouse for immune support, collagen production (joint and skin health), and recovery from intense workouts. If you’re low on these, your body simply won’t perform at its best. Everything we create at 191 Nutrition is designed to help men build muscle, improve stamina, boost immunity, and support joint health. It’s not about gimmicks or quick fixes; it’s about giving your body exactly what it needs to function like a high-performance machine. For me, performance is an obsession, and 191 Nutrition is simply an extension of that mindset. If you’re serious about fitness, wellness, and longevity, you have to start with what you put into your body.
Which of your supplements would you recommend for men looking to build strength and endurance?
For men looking to build strength and endurance, I always recommend focusing on the foundational supplements that actually make a difference—no gimmicks, just science-backed essentials. At 191 Nutrition, we focus on providing exactly what your body needs to train harder, recover faster, and perform better. First, Whey Protein is a must. Protein is the building block of muscle, and if you’re training hard but not getting enough protein, you’re limiting your gains. Whey protein helps with muscle repair, growth, and recovery, making sure your body has the fuel it needs after intense workouts. Plus, it’s quick-digesting and highly bioavailable, meaning your muscles absorb it efficiently. Second, Creatine is one of the most researched and effective supplements for strength and endurance. It increases ATP production, which is your body’s primary energy source during high-intensity training. This means more power, better muscle endurance, and faster recovery. If you want to lift heavier, push harder, and recover quicker, creatine is a no-brainer. Third, Magnesium is something most men don’t even think about, but it plays a huge role in muscle function, energy production, and recovery. It helps reduce muscle cramps, improve sleep, and optimize testosterone levels—all of which are critical if you’re training regularly. Most people are deficient in magnesium, especially those with high training loads, so supplementing it can dramatically improve performance and recovery.
Recovery is just as important as training. How do your products, like the Rest and Recovery tablet, help men improve their sleep and muscle repair?
Recovery is just as important as training, and most men don’t realize that you don’t get stronger in the gym—you get stronger when you rest and recover properly. That’s why we created the Rest and Recovery tablet at 191 Nutrition—to help men optimize sleep, muscle repair, and overall recovery so they can perform at their best every single day. A key part of this is Magnesium and Zinc, two minerals that are absolutely essential for deep sleep, muscle relaxation, and testosterone production. Magnesium helps reduce muscle cramps, improve sleep quality, and regulate stress, while Zinc plays a crucial role in immune function, hormone balance, and muscle recovery. Traditionally, Indian diets included Foxnut (Makhana), which is naturally rich in magnesium, but over time, people have moved away from these nutrient-dense foods, leading to deficiencies that impact sleep and recovery. Our Rest and Recovery formula is designed to bring these essential nutrients back into your routine in a way that fits modern lifestyles. It helps with deeper, more restful sleep, so your body can repair muscle tissue, balance hormones, and wake up feeling refreshed instead of fatigued. When you recover properly, you’re not just preventing injuries—you’re optimizing performance, strength, and endurance. At 191 Nutrition, we don’t believe in shortcuts—just science-backed, performance-driven nutrition that helps men train harder, recover faster, and feel their best every day.
There’s a growing trend of men paying more attention to holistic health. How does 191 Nutrition align with this shift?
Post-COVID, people finally started recognizing the importance of vitamins and overall health. Before the pandemic, supplementation was mostly seen as something for bodybuilders or athletes. But after COVID, people realized that nutrition isn’t just about building muscle—it’s about strengthening immunity, improving energy, enhancing recovery, and promoting longevity. At 191 Nutrition, we align perfectly with this shift towards holistic health. Our supplements aren’t just about aesthetics or performance—they’re about helping men feel, function, and live better for the long run. Take Vitamin D3, B12, Magnesium, and Zinc—nutrients that were ignored by most men before COVID. But now, it’s well-known that Vitamin D3 is essential for immunity and hormone balance, B12 is crucial for energy and brain function, Magnesium supports deep sleep and stress relief, and Zinc plays a key role in recovery and testosterone production. These aren’t just for fitness enthusiasts—they’re for every man who wants to perform at his best in daily life. We believe supplementation should support every aspect of a man’s health—muscle growth, endurance, sleep, immunity, joint health, and overall well-being. Our goal at 191 Nutrition is to provide clean, science-backed supplements that fit into the modern man’s lifestyle, helping him not just train harder, but live longer and stronger.
Beyond supplements, what are some key nutrition tips men should follow for long-term wellness?
Beyond supplements, the foundation of long-term wellness is built on proper nutrition and lifestyle choices. No supplement can replace a bad diet, so men need to focus on fueling their bodies like high-performance machines. Here are some key nutrition principles every man should follow:
First, prioritize protein in every meal. Whether your goal is building muscle, staying lean, or just maintaining energy levels, protein is essential for muscle repair, metabolism, and overall strength. Good sources include lean meats, eggs, fish, paneer, lentils, and whey protein if you’re not hitting your daily intake.
Second, don’t overlook micronutrients. The Indian diet traditionally had nutrient-dense foods like foxnuts (makhana), seeds, nuts, and fermented foods, but today, most people rely on processed foods, which lack essential vitamins and minerals like magnesium, zinc, vitamin D3, and B12. This is why supplementation has become important—to fill those gaps that modern diets have created. Third, eat for longevity, not just for today. Many men focus only on short-term gains—bulking up or cutting weight—but real health comes from balanced meals that support gut health, hormonal balance, and overall well-being. That means focusing on whole foods, avoiding excessive sugar and processed junk, and staying hydrated.
Lastly, eat at home as much as possible. Cooking your own meals gives you control over ingredients, portion sizes, and overall quality. Restaurant and takeout food are often loaded with excess oils, sodium, and preservatives that can wreck your long-term health.
At 191 Nutrition, we believe in a performance-first approach to health—where food is seen as fuel and the goal isn’t just to look good, but to feel strong, stay disease-free, and live Longer.

Looking back on your journey, what has been the most fulfilling moment in your career so far?
Looking back on my journey, there have been many milestones that I’m proud of—becoming India’s first 10-time national champion in Brazilian Jiu-Jitsu, the first Indian to earn a competition Black Belt in BJJ, a 4-time world champion, and coaching India’s first Road to UFC winner, Anshul Jubli. These achievements were all incredible moments, but if you ask me what I’m most proud of, it’s something much deeper than titles and trophies. The greatest achievement of my career is coaching women who have used their BJJ and MMA training to defend themselves in real-life situations. Nothing is more fulfilling than seeing someone I’ve trained use their skills to protect themselves when it truly mattered. One story that stands out is of a former student who was attacked by a cab driver. She had trained with us for a while, and one night, while taking a cab home, the driver tried to assault her. Instead of panicking, she reacted instantly—she locked in a triangle choke, put the driver to sleep, and escaped unharmed. That moment proved to me that what we do at Crosstrain Fight Club is more than just a sport—it’s about giving people the ability to protect themselves, to take control in dangerous situations, and to walk through life with confidence. Titles and records come and go, but empowering people—especially women—to fight back and stand up for themselves is something that will always mean the most to me.
What’s next for 191 Nutrition? Do you have plans to expand the product line or venture into other areas of wellness?
At 191 Nutrition, we are just getting started. While our current product line focuses on performance, recovery, and overall health, the next phase is about taking men’s wellness to the next level. We don’t just want to help men train harder—we want to help them look, feel, and perform at their absolute best in every aspect of life.
Going forward, we are expanding into hair, skin, and testosterone optimization, as these are crucial but often overlooked areas of men’s health. Hair and skin health are directly linked to nutrition, and most men don’t realize that deficiencies in biotin, collagen, and key vitamins like A, C, and E can affect their appearance and confidence. We’re working on products that will support strong hair, clear skin, and overall vitality from within.
Another big focus is testosterone support. As men age, testosterone levels naturally decline, which impacts energy, strength, recovery, and even mental clarity. We’re formulating supplements with scientifically-backed ingredients like Ashwagandha, Zinc, Vitamin D3, and Fenugreek to help men maintain optimal hormone levels and peak performance.
And of course, we are doubling down on Creatine—one of the most powerful and proven supplements for strength, endurance, and brain function. Our goal is to create the highest quality creatine product available, ensuring that athletes and fitness enthusiasts get maximum power, performance, and recovery benefits.
The future of 191 Nutrition isn’t just about supplements—it’s about building a complete ecosystem for men’s wellness. From training to recovery, from performance to longevity, we want to be the go-to brand for men who are serious about their health.
If you could give one piece of advice to men looking to improve their fitness, health, and overall lifestyle, what would it be?
Make discipline your default.
Most men struggle because they rely on motivation, but motivation is temporary—it comes and goes. Discipline, on the other hand, is what keeps you going when you don’t feel like it. You shouldn’t wake up and debate whether or not you should train, eat clean, or take care of your body. It should be non-negotiable, just like brushing your teeth.
If you truly want to be stronger, healthier, and better, stop overcomplicating things. Move every day, eat real food, prioritize recovery, and stay consistent. Stop waiting for the perfect time to start—just start. Because the men who succeed aren’t the ones who do everything perfectly; they’re the ones who show up, day after day, no matter what.
