About John Parlanti
Personal trainer, based in Clapham, coaching busy adults to lose fat, build muscle and keep it off.
I'm John Parlanti, a personal trainer based in Clapham, London. I work exclusively in-person, with no online coaching, because I believe the fastest, most reliable way to get real results is with a coach in the room with you, every session. I offer 1-to-1 and 2-to-1 personal training, plus mobile sessions at home or outdoors.
My focus is helping busy adults lose body fat, build muscle and, most importantly, keep the results once they've got them. That means training that fits realistically around work, family and everything else, not a programme that only works if your life stops for it.
Every client starts with a free trial session so I can talk through your goals, assess where you're starting from, and build a plan that's actually realistic for you, whether you're completely new to training or getting back into it after a break.
I'm based at a gym on Northcote Road in Clapham Junction, with outdoor sessions too depending on what suits your programme: an easy, direct trip whether you're coming from Clapham, Battersea, Balham or Wandsworth. See the full address →
My Story
Coaching Built on Experience
Fitness didn't always come naturally to me. I wasn't always in shape. At one point I weighed over 120kg, and I know what it feels like to struggle with consistency, confidence and motivation.
For about five years I let my health slide. I told myself I was too busy, that it was fine to skip the gym, that other things mattered more. It took a long time to realise that wasn't the life I wanted to live: avoiding cameras, permanently exhausted, my blood pressure through the roof.
Then COVID happened. Time away from work and other people gave me the space to properly assess my situation, and I decided to change everything: my diet, my training, my health. I set up a few weights in the garden, gave myself daily step targets, and started tracking every session properly. Over the next four months I lost 20kg while building muscle, and felt better than I had in a decade.

That transformation is what inspired me to become a coach. I know what it's like to be on the other side of it, and I wanted to help other people get there too, for themselves, their families and the people around them.
Fitness wasn't new to me before that, though. I grew up around sport: athletics, football, swimming, even if structure and discipline weren't always consistent in my own life. I entered the fitness industry in 2007, working across public and private fitness centres in both gym and pool environments, and over the years I've coached everyone from complete beginners to busy professionals and competitive athletes.
