Momentum Fitness

At the RKC, we have always believed that mastery is not a destination, but a lifelong pursuit. Our system has long emphasized strength, mobility, precision, and the ability to move with both power and intention.

It is in that spirit of excellence and innovation that we are proud to announce the next evolution in kettlebell education:

RKC Kettlebell Ballet Certification

For years, we have taught that true kettlebell training is not simply about lifting weight, but about expressing strength through efficient, graceful movement. Ballet, with its unmatched demands for mobility, endurance, balance, posture, and technical precision, represents a natural progression in that philosophy.

This groundbreaking certification is designed to blend the elegance of classical dance with the tension, relaxation, and force production principles that define Hardstyle training. The result is a system that develops not only strength and resilience, but poise, artistry, and total-body control.

Candidates will be tested in a series of foundational and advanced skills, including the Clean and Press performed in a plié, the Get-Up from a split position, the Interpretative Sn**ch Dance, and of course, the highly anticipated Ballerina’s Carry, in which participants will leap through the air while holding their bodyweight in kettlebells.

This certification will challenge participants to demonstrate mastery under load while maintaining technical excellence, grace of movement, and composure throughout. As always, our standards will remain high. This is not choreography for its own sake. This is strength education refined to its highest artistic expression.

We believe this new model has the potential to transform the industry and expand the reach of kettlebell training to an entirely new audience.

Join us as we continue to lead from the front and bring this powerful new system to market.

Strength. Mobility. Grace.
Official details coming soon.

Space is limited. Soft slippers recommended. Pointe experience preferred, but not required.

I’m getting desperate trying to find someone who repairs and/or maintains Concept 2 rowers.
Posting this ridiculous video for attention, please reach out if you know of someone!

“Stop training for likes and start training for life… because the algorithm won’t help you when you throw your back out picking up your kid.” 💀🔥

So I made a completely unhinged video of myself flipping kettlebells, juggling them, balancing them on my head, and doing all kinds of wildly unsafe “circus tricks.” 🤡

Before anyone calls my wife, my insurance company, or the NYPD… yes. It’s obviously AI. Because I personally enjoy having teeth. And shoulders. And a functioning future.

But here’s the sad truth:
These are the kinds of posts that go viral.
These are the workouts that get likes, reshares, and comments like:
“BRO WHAT WEIGHT IS THAT??”
“🔥🔥🔥”
“MY ROTATOR CUFF JUST LEFT THE CHAT.”

Meanwhile, the real work?
The boring stuff?
The unsexy, repetitive, disciplined grind?
That gets about 7 likes. Three of them are your mom. One is your chiropractor.

Here’s the reality nobody wants to hear:
Random workouts = random results.
“Muscle confusion” is just your body being confused why you keep doing dumb things.

Real progress comes from consistency.
From mastering the basics.
From showing up even when it’s not exciting.
From doing swings, squats, presses, and get-ups so many times that your neighbors think you’re training for a kettlebell apocalypse.

Because true mastery isn’t flashy. It’s built quietly.
Technique, strength, and resilience will outlast every 10-minute-of-fame influencer chasing the algorithm like a squirrel chasing a laser pointer. 🐿️

So forget the circus.
Learn the fundamentals.
Do the work.
And keep doing it long after the internet moves on to the next shiny object.

Your future self will thank you.
Your joints will thank you.
And your dentist will definitely thank you. 😁

Pregnancy is one of the most incredible things the human body can do. It’s also one of the most confusing times when it comes to fitness. One minute someone is told to “stay active,” the next minute they’re told to avoid everything. Meanwhile, the internet is full of influencers doing circus tricks at 8 months pregnant. Let’s be honest… that’s not what most moms need. 😅

Pre and post natal personal training is not about six-pack selfies. It’s about helping women move better, feel stronger, reduce pain, support the pelvic floor, and rebuild confidence before and after baby. Done right, it can make pregnancy smoother, recovery faster, and long-term health stronger. This is real life strength, not algorithm strength.

But here’s the catch… this population requires real education. Trainers need to understand breathing, core and pelvic floor health, posture, and how the body changes during and after pregnancy. Good intentions are not enough. Proper certification and continuing education are essential if you want to truly help instead of guess.

That’s why we’re excited to host Anette Lang, one of the most respected pre and post natal educators in the world. With decades of experience and thousands of coaches trained, Anette brings practical, real-world knowledge that you can use immediately. No fluff. No gimmicks. Just smart, effective coaching.

👉 Join us April 19 in NYC for Anette Lang’s Pre/Post Natal Certification.
If you want to grow as a coach, serve more clients, and stand out in a crowded industry, this is your chance.

Because moms deserve more than random workouts… and trainers should be more than random coaches. 💪

Update on our Air Conditioning situation

We know it’s hot in the gym. We feel it too. And we want you to know that we are doing everything we possibly can to manage the situation. We have additional fans arriving and are actively working to keep the environment as comfortable and safe as possible while we search for a real solution.

The truth is, our current HVAC system is no longer repairable. It is obsolete, and replacement parts are no longer manufactured. Every dollar we’ve spent over the past few years has been temporary life support on a system that is now completely beyond saving.

Unfortunately, the building and our landlord have refused to assist or even meaningfully engage in a solution. A full replacement will cost well into the high six figures, which is simply not feasible for a small, locally owned business like ours. After 16 years serving this community, this situation could genuinely threaten our ability to stay open if we cannot reach a fair agreement.

We have proposed contributing a significant portion toward a new system, but the landlord continues to insist that the responsibility is 100% ours.

To those of you who are sticking with us during this time, we truly cannot thank you enough. Your support means everything to our team and to our family. Momentum Fitness has always been a community first and a business second, and your loyalty reminds us why we built this place from the ground up.

To those who have chosen to leave or request refunds, we understand and we are truly sorry. Please know this situation is not the result of negligence or inaction. We care deeply about your experience and your safety, and we are fighting hard behind the scenes to resolve this as quickly as possible.

We remain hopeful that a solution can be reached so that we can continue serving the Upper West Side for many years to come.

Thank you for your patience, your understanding, and your continued support.

— Marco & the Momentum Fitness Team

Momentum Family 💙

After a lot of thought, we’re taking Momentum Fitness off ClassPass. We’ve loved meeting so many of you through it since 2015…but the reality is we can’t keep our doors open with what ClassPass pays small studios.

So we made direct group fitness more flexible (and more affordable):

✅ 24-Class Pack = $20/class
✅ Classes never expire (and can be shareable with friends/family)
✅ Monthly options (month-to-month, cancel anytime):
• 4 classes = $100
• 10 classes = $185 ($18.50/class, our lowest rate)
• Unlimited = $250

🎁 Bonus: Buy directly (package or subscription) and get a FREE InBody scan ($50 value) to help track your progress.

We’ve been proudly serving the UWS since 2010, and your support helps keep a true mom & pop gym alive in NYC. Thank you for being part of this community, and let’s make 2026 our strongest year yet. 💪✨

DM us or stop by the front desk to get set up.

The best coaches never stop being students. 📚💪

Continuing education isn’t just about collecting certs – it’s about becoming the kind of coach who can actually solve problems for real people.
• Every course you take gives you more tools and modalities to tackle your clients’ pain points, plateaus, and limitations.
• It helps you serve a wider variety of people and confidently market yourself to new niches.
• You build powerful connections with instructors and fellow pros that can open doors you didn’t even know existed.
• And in a sea of “certified trainers,” it shows you’re truly investing in yourself, your craft, and your clients’ results.

We’ve got a full lineup of certifications and workshops coming to Momentum Fitness in 2026 — from kettlebells and macebells to mobility and recovery — all in a beautiful, fully equipped facility in the heart of Manhattan’s Upper West Side.

When it rains, it pours… literally. 💦

An AC pipe burst in our gym and we’re currently in repair mode, so please excuse our appearance for a bit. What we can promise is that we’re 100% on top of it—just like we ask you to be on top of your health.

This whole situation is a perfect analogy for your body:

You don’t wait for a pipe to burst before you start caring about the building.
You maintain it, reinforce it, and make it more resilient so when something does go wrong, it can handle the stress.

That’s exactly what consistent exercise and strength training do for YOU.
• Life is full of surprises—injuries, stress, long days, family emergencies, career curveballs. A strong body helps you persevere through anything that gets thrown your way.
• Putting in the work now doesn’t just build muscle; it sharpens your mind, boosts your confidence, and gives you the mental focus to handle problems instead of spiraling over what you “can’t” do.
• Training for real life and longevity will always beat chasing mirror muscles and show-off workouts. We’re here to help you move better, feel stronger, and stay ready for the unexpected—inside and outside the gym.

Just like we’re reinforcing the gym so it can keep serving the community, we want to help you reinforce your foundation so you can keep showing up for the people and things that matter most. 💚💙
