Let's be honest from the start: we run a private training studio in Blackheath, so you know where we stand. But we'll make the comparison fairly — commercial gyms genuinely suit some people, and a private studio genuinely suits others. The trick is knowing which one you are before you spend a year finding out.
What each one actually is
A commercial gym sells access: equipment, space, and (usually) classes, shared with everyone else who bought the same membership. What you do with it is up to you.
A private studio sells outcomes: the room, the equipment and — crucially — the coach are dedicated to you for the hour. At KD there are no members and no crowds; every session is one client (or one couple) and one coach, with a programme written specifically for you.
Five honest comparisons
1. Attention
In a commercial gym, guidance is what you bring with you — a plan from the internet, a class instructor's general cues, perhaps a PT session on a busy floor. In a private studio, every rep of every set is coached: technique corrected in real time, loads adjusted to how you're moving today, exercises swapped when something doesn't suit your body.
2. Time
The hidden cost of a busy gym is waiting: for the squat rack, for the bench, for the cable machine at 6pm. A private hour is exactly that — a full hour of training. Most clients get more genuine work done in 60 private minutes than in 90 crowded ones.
3. Consistency
This is the quiet decider. Memberships are easy to buy and easy to ignore — most lapsed gym-goers don't cancel, they just stop going. A booked session with a coach who knows you, expects you and plans around you is dramatically harder to skip. Results follow attendance, and attendance follows accountability.
4. Comfort
Plenty of capable, motivated people simply hate training in public — beginners, returners, anyone self-conscious about their starting point, anyone rebuilding after injury or navigating midlife changes. If the room itself is the barrier, removing the room removes the barrier. Privacy isn't a luxury here; it's the reason training finally sticks.
5. Cost
A commercial membership is cheaper per month — no argument. The fairer comparison is cost per result. A membership used twice a month with no plan is expensive however little it costs; coached sessions that actually happen, progress week on week and change how you feel are worth pricing honestly. Our prices are published openly on the pricing page, including block discounts — no phone call required.
Who a commercial gym genuinely suits
- Experienced lifters who programme for themselves and love the buzz of a busy floor
- People whose budget is the deciding factor right now — moving beats not moving
- Class-lovers who thrive on group energy
Who a private studio suits
- Beginners and returners who want to start properly, without an audience
- Busy people who need maximum result per hour
- Anyone whose consistency collapses without accountability
- Post-injury and over-50s clients who need training adapted to them
- Anyone who's been 'meaning to get back to the gym' for over a year
Try the difference
If you've read this far, you probably already know which side you're on. The clean way to find out for certain: book a free 30-minute introductory session at our Blackheath studio — two minutes from the station, completely private, no obligation. Worst case, you've lost half an hour and gained a clear answer.
