Kettlebell Training on the Upper West Side

Fifteen certified kettlebell instructors. Dedicated kettlebell classes capped at ten people. The gym where other trainers come to get certified. Whether you're picking up a kettlebell for the first time or chasing a heavier press, this is where serious kettlebell training happens on the Upper West Side.

What Sets Kettlebell Training Apart

A kettlebell is a cast-iron weight with a handle on top. That simple design lets you swing, press, squat, and carry it in ways that dumbbells and barbells can't replicate, and it trains your entire body in a single movement.

Kettlebell training splits into two categories. Ballistic movements (swings, cleans, snatches) build explosive hip power, grip strength, and cardiovascular endurance. Grinds (presses, squats, Turkish get-ups) build raw strength, shoulder stability, and total-body control. Most sessions use both, which is why a forty-minute kettlebell workout can replace an hour of separate strength and cardio training.

What makes it different from picking up weights at a commercial gym is the coaching. A properly taught kettlebell swing is a precise hip hinge that loads your glutes and hamstrings while sparing your lower back. Taught poorly, it's a recipe for injury. That's why certification matters.

Momentum's kettlebell program is built around the RKC (Russian Kettlebell Challenge) system, one of the most rigorous kettlebell certifications in the industry. It's a two-day gauntlet of technique testing, strength standards, and live coaching assessments. Candidates fail if their form or teaching ability doesn't meet the standard. Momentum's owner, Marco Guanilo, holds a Master RKC and leads the RKC and HKC certification courses hosted right here in the gym. The trainers on this floor learned from the same system, and several hold advanced RKC II or dual RKC/SFG credentials.

Once you have the kettlebell fundamentals dialed in, the training evolves. Double kettlebell work (two bells at once) adds a coordination and loading challenge that changes the game for clients who've outgrown single-bell programming. The gym stocks a full range of RKC kettlebells from 8kg to well beyond what most people will ever need, so you'll never outgrow the equipment.

Who It's Best For

You sit at a desk all day and your back reminds you every evening. You don't have time for a long gym session, but you need something that actually builds strength and loosens you up in the same workout.

You used to play a sport and you miss training that feels athletic. Explosive, coordinated, skill-based. Not just grinding through sets on a leg press.

You're a parent and you want the kind of functional strength that shows up when you're carrying a kid in one arm and groceries in the other without thinking about it.

You've been doing the same gym routine for years and you're bored. Kettlebell training is a skill that progresses. There's always a heavier bell, a harder variation, or a movement you haven't learned yet.

You're a woman who wants to build real strength without a bodybuilder-style program. Kettlebell training builds lean, functional power through movements that work your entire body. Most of Momentum's female clients start pressing heavier than they expected within months because the progression is skill-based, not just load-based.

You run, cycle, or do endurance training and you need posterior chain strength (glutes, hamstrings, back) without adding bulk or spending an hour in the weight room. The gym is a block from Central Park, which makes it easy to pair your runs with coached strength work on the same day.

More Than Just Strength

Clients who train with kettlebells consistently report stronger grip, better posture, and less lower back pain, often within the first month. The posterior chain emphasis corrects the imbalances that desk sitting builds over time.

A 2010 ACE study found that a kettlebell snatch protocol burned roughly 20 calories per minute, comparable to cross-country skiing uphill. That efficiency is built into how Marco Guanilo (Master RKC) programs kettlebell sessions: ballistic movements keep your heart rate elevated while you're building strength, so clients get conditioning and strength work in the same session instead of splitting their week between the two. Marco has spent over 20 years refining this approach, and he's one of the people who certifies other RKC instructors internationally. The programming his clients follow isn't pulled from a textbook. It's built on two decades of coaching kettlebell athletes and everyday clients through the same system.

Research from the American Physiological Society (2024) found that older adults who trained with kettlebells for six months gained muscle mass, grip strength, and upper leg strength. Kate Edwards (RKC + SFG) is dual-certified across the two hardest kettlebell systems in the industry, which means her programming draws from both traditions. For clients who have outgrown single-bell work, her double kettlebell programming adds a coordination and loading challenge that accelerates strength gains in ways that single-bell training plateaus on.

There's a coordination and body awareness component that most people don't expect. Movements like the Turkish get-up take you from lying on the floor to standing with a weight locked overhead, training stability through every joint along the way. Geoffrey Hemingway (RKC Team Leader) coaches these complex movements with the precision that his Team Leader credential demands, breaking each position down so clients build full-body control, not just full-body fatigue. That kind of training translates directly to how you move outside the gym.

How Momentum Delivers Kettlebell Training

One-on-one with Momentum's personal trainers means your program is built around you, not a generic template. Your trainer teaches the foundational movements (the swing, the clean, the press, the get-up) at your pace, correcting form in real time. As your technique improves, the weight goes up, the movements get more complex (loaded carries, double kettlebell complexes, heavier snatches), and the programming evolves. Sessions aren't random workouts. They're structured progressions designed to build on each other.

The depth of kettlebell expertise on staff is uncommon. Marco Guanilo (Master RKC) is one of the people who certifies other kettlebell instructors internationally. Kate Edwards holds both the RKC and SFG, dual-certified across the two hardest kettlebell systems. Geoffrey Hemingway is an RKC Team Leader. Jen Ares-Cruz, Hernan Quintanilla, and Bradford Shreve all hold the advanced RKC II. When your kettlebell instructor corrects your swing, they're drawing on credentials that most gyms don't have on staff at all.

Group classes bring kettlebell training into a coached, small-group setting. ABC's of KB's with Geoffrey Hemingway teaches the foundational lifts (deadlifts, cleans, squats, presses, rows, loaded carries) with progressive technique at every level. Kettlebell Power & Play with Sara Villagio is a more accessible, energy-driven class built on functional kettlebell patterns. Both are capped at eight to ten people, which means your instructor has eyes on your form for every rep.

Early Morning HIIT, Full Body HIIT, and Strength & Conditioning also incorporate kettlebells alongside other tools for clients who want variety.

No membership required. Buy a personal training package or a class pack. Both are shareable with friends or family, and neither expires.
