Why People Switch
The Gym Membership You Stopped Using.
Wandering between machines with no plan
A coached session already planned for you
Same routine until you quit out of boredom
Constantly varied workouts, every session different
Nobody notices whether you show up
Coaches and classmates who expect you
Months in, and nothing looks different
Progress you can measure and feel
1999
Coaching Newtonville since
Designed For This Age
You get watched, corrected and pushed.
Bootcamp runs inside a martial arts school, and that changes the coaching completely. Groups stay small enough that someone is watching your form, scaling each movement to your body, and telling you when to push and when to back off. It's the same standard of instruction our black belts train under, applied to fitness, fat loss and conditioning.
Fitness & Fat Loss
Sessions built to burn, build and change how you look and move.
High-Intensity, Varied
Never the same workout twice, so your body never gets to coast.
Expert Coaches
Black-belt instructors correcting form rep by rep.
Supportive Community
A room of adults pulling in the same direction, at every level.
Flexible Program
Class times that fit around work. Ask us for the current schedule.
Visible Results
Strength, stamina and body composition you can actually track.
45 Minutes That Count.
Dynamic Warm-Up
Joints, hips and shoulders prepped so nothing gets tweaked.
Movement Prep
The day's movements taught and scaled to your level.
The Work
Intervals, bag work, kicks, bodyweight strength. Different every session.
Finisher
One honest push, with a coach counting for you.
Cool Down
Breathing and mobility so you can still walk tomorrow.
Every Level
every movement has an easier and a harder version
You are never the odd one out. Coaches adjust the workout live.
Within The First Few Weeks
What Members Notice First
The first changes aren't on the scale. They're in how your week feels.
More energy at 3pm, without the extra coffee
You actually show up, because people expect you
Stairs, groceries and kids get easier to carry
Clothes fit differently within the first few weeks
Stronger Than When You Walked In
Bootcamp is built for adults who want to feel capable again, not for people who are already fit.
Confidence You Earn
Every week you do something you couldn't the week before.
A Coach In Your Corner
Somebody notices your progress and pushes you toward the next one.
A Gateway To Karate
Plenty of bootcamp members end up on the karate mat too.

So happy we found this place, I wish I had started my kids even younger!"
