STRENGTH
TRAINING.
MADE SIMPLE.
Private coaching gyms in Thame and Fleet Marston (Aylesbury) for adults who want to feel strong and capable again. Small groups, a coach in the room every session, and a team that keeps you showing up.
You don't need another gym membership.
You've probably been here before. A new routine, a few good weeks, then life gets busy and it quietly fades. That's not a willpower problem. It's usually a support problem.
At Powerhouse, training stops being something you have to figure out and push through alone. You get a plan, a coach, and a group of people who notice when you're not there.
- × You keep giving up on your health goals
- × Your energy and motivation are low
- × You're nervous about starting again
- × You don't know what to do when you get to a gym
- × You feel out of place in a normal gym
- × You train alone, with no one holding you accountable
- × You miss being part of something
Strength training, made simple.
No complicated programmes. Just coached strength work in small groups, built around where you are right now, so you get stronger, fitter and more confident week on week.
Strength first
More strength means better fitness, more energy, a metabolism that works for you, and body fat that actually stays off. Simple, and it works.
StrengthGroup personal training
Personal coaching, inside a small group. A coach is in the room with you every session, and every session is 45 minutes.
Small groupsCoached, not left alone
1:1 coaching support through our app, ongoing education and regular check ins, so you're never working it out by yourself.
SupportTeam first
Always aiming for better. Earned, together. A friendly, ego free environment where everyone thrives, whatever their starting point.
CommunityYou used to be consistent. You can be again.
We built Powerhouse for adults aged 35+ who were once fit and active, then work, family, injuries and life got in the way. You don't want a grind culture or a body transformation plan. You want to feel strong, energetic and capable again, without being judged for where you're starting.
That's why we're not a bodybuilding gym or a place with a crowded floor and no coaching. We're a results based coaching facility, and we've coached over 1,000 locals.

People who've done exactly this.
"So glad I signed up to the 6 week challenge which popped up on my Facebook. I'm now a full member, achieving incredible physical and mental results. Flexible timetable, friendly encouraging atmosphere, way better than any gym I've joined."
"I have always loved exercising but struggled in other gyms with people pushing weight loss as the goal. The coaches at Powerhouse listened to what I wanted and supported me throughout. I'm now the strongest, healthiest and happiest I have ever been."
"Powerhouse offer fantastic coaching and classes. You're really encouraged and supported to work hard and achieve your goals. Well worth investing your time and money into a gym that pushes you and holds classes tailored to build your strength."
