Peter: 80lbs Weight Loss (Markyate)
“In the last 12 months I’ve lost almost 80 pounds (5.5stones) with Juan’s help. I find both sport and life so much easier now.
The important thing I’ve learnt is that if you’re serious, you’ve going to be spending a lot of time with your personal trainer. So find someone you get on well with and Juan’s a nice guy to spend time with.”

Jennifer: Strength, Tone & Body Shape (St Albans)
“I’ve been training with Juan since 2013 and the results have been incredible. My body shape has completely changed, I’m stronger, fitter and more toned. Juan pushes me to my limit safely and motivates me more than I ever could on my own. His passion for fitness is infectious. He’s the best personal trainer in St Albans, without question.”

Daniel: 5 Stone Lost (Rennie Grove Biggest Loser Winner)
“Juan coached me through the 19‑week Rennie Grove ‘Biggest Loser’ competition and helped me lose over 5 stone (23% body fat). He adapted every exercise to my ability and pushed me outside my comfort zone safely. Each week I got fitter, stronger and more confident. Juan’s support was constant, he checked in, motivated me and kept me focused. I couldn’t have won without him.”

Paul: Weight Loss, Strength & Mobility (Bendish)
“Juan helped me lose weight, get fitter and feel younger. He created a personalised programme that improved my strength, mobility and diet. He tracks progress with photos and measurements, and his encouragement keeps you going. Juan’s enthusiasm for fitness is inspiring, he’s now more than my trainer, he’s a friend. I recommend JSM Fitness to anyone serious about improving their health.”

Vicky: 20lbs Lost & 2 Dress Sizes Down (St Albans)
“I hired Juan because I wanted to feel fit and confident before turning 40. After just four months, I’ve lost 20lbs, dropped two dress sizes, and have more energy than ever. The nutrition plan and personalised workouts have completely transformed my body. Juan is flexible, supportive and worth every penny, I only wish I’d started sooner.”
