As an Ironman certified coach, I lead an outdoor fitness community with a no-excuses philosophy. We specialize in group training, from running squads to HIIT and Animal Flow, prioritizing smart recovery to keep you ready for every challenge.

Training alongside the best. A throwback to a running session with the legendary MS Dhoni. It's a privilege to share my knowledge of fitness and movement with top-tier athletes.

As an expert coach for the Reebok Running Squad, I specialize in long-distance running and functional training. My goal is to build stronger, more resilient runners through a holistic approach to fitness.

1-on-1 Personal Training

Studio sessions in Mukherjee Nagar and outdoor workouts at Lodhi Garden

I give you one-on-one training focused on safe technique, injury rehab, and functional strength using kettlebells, TRX, and barefoot methods, all in my private studio or outdoors.

1,500-4,000

per session

This is what it feels like to push your limits at the roof of the world. As a coach, I don't just prepare you for the distance; I prepare you for the environment. This shot from the Ladakh Marathon captures the essence of high-altitude race training and the incredible strength you'll build with us.

The pack energy is real. Here's our squad taking on an early morning run at Kartavya Path in Delhi. Training for an endurance race can be a lonely journey, but with us, you're never running alone. We sweat, struggle, and succeed together.

My coaching is not just about logging miles. We build strong, resilient athletes from the ground up with functional strength training. Here, our group uses TRX for a full-body workout, improving core stability and muscular endurance which is crucial for running.

The smiles say it all. This is the moment of pure joy after conquering the Ladakh Marathon. My goal is to get you across the finish line, feeling strong and proud. These medals are a testament to months of hard work, dedication, and smart training.

For my Ironman and triathlon athletes, the grind includes the pool. This is a look at a 3,500m long swim session, focusing on building endurance and perfecting technique in the water. I create balanced training plans that cover swim, bike, and run.

This is our 'Chak De' moment. Our community runs are more than just training; they are a celebration of fitness, friendship, and spirit. Here's our group during a special Independence Day run at Lodhi Garden, showing our collective energy and pride.

Endurance & Race Coaching

Group sessions at Lodhi Garden, Kartavya Path, and across Delhi NCR

I coach you for marathons, ultramarathons, high-altitude races, and Ironman with structured plans, strength workouts, nutrition advice, and group training sessions.

3-10K

per month (group coaching)

This is what it feels like to run with us in Ladakh. A participant pushes through on a high-altitude trail run, with the stunning mountains and a distant monastery creating an unforgettable backdrop.

The pure joy of achievement. Three members of our team proudly show off their finisher medals after conquering the Ladakh Marathon, smiles all around. This is the moment all the hard work pays for.

As your coach, I am right there with you. Here I am at the Ladakh Marathon, ready to support our team and celebrate every victory on the course.

We made it to the top. Our group stands proudly at the iconic Khardungla Pass sign, the gateway to Siachen, at a breathtaking altitude of 17,982 feet. This is a key milestone in our high-altitude fitness trip.

Fitness should also be fun. Here, one of our team members celebrates with a playful cartwheel in the cool river water after a tough day of training, with the beautiful mountains of Ladakh in the background.

The power of community. Our entire running squad gathers for a group photo at the Dream Runners Half Marathon in Chennai, celebrating a successful event together. We train as a team and we win as a team.

Fitness Expeditions & Retreats

Destination marathons and fitness retreats across India

I take you on fitness trips where we train, run marathons, and do workouts in places like Ladakh or Berlin, mixing travel and exercise with hands-on coaching.

20-80K

per person per expedition

This is the energy of our running squad. We are a community of all ages and fitness levels, pushing each other to get stronger with every step. We train outdoors, embracing the elements and the joy of movement together.

Strength comes in many forms, and here, it comes with a smile. My functional bootcamp sessions use equipment like sandbags to build real-world power. It's about becoming strong for life, not just for the gym.

Running with pride. Our community often comes together for special events, like this Independence Day run. It's more than just fitness, it's about sharing powerful moments and celebrating together as a squad.

This is the fit fam. After a tough weekend session, it's all about the smiles and the shared sense of accomplishment. We support each other, push each other, and grow stronger together.

Group Fitness & Bootcamp

Outdoor bootcamps at Lodhi Garden, Delhi

I run outdoor group bootcamp sessions in Delhi parks with functional workouts, barefoot training, and a focus on real-life strength and injury prevention for all fitness levels.
