Leap Into Fitness Exercise Studio - (Near Hackney, UK)

5 /5 Thomas French: I’ve been training with JJ for several years, primarily to build the strength foundation for distance running. JJ consistently delivers not just as a trainer but as a genuine coach—friendly, supportive, and highly knowledgeable. He crafted a strength plan that perfectly complements my running schedule, allowing me to balance three focused gym sessions a week with my distance training. Seeing JJ a few times each month keeps me motivated and ensures I’m progressing effectively, both in the gym and on the road. Highly recommended for anyone looking to take their running or overall fitness to the next level.

5 /5 Lucy Lu: Joining this gym has been a total game changer. From day one, the trainers took the time to understand my goals and my lifestyle. Classes change monthly for variety. The trainers here are absolute pros. After just a few weeks, I noticed real changes. If you’re serious about getting in shape and want guidance that truly delivers, stop scrolling and sign up! It’s worth every penny.

5 /5 Tatjana: Five stars isn’t enough for JJ’s Leap into Fitness. I’ve been a loyal client for nearly two years, doing both PT and the weekly classes, and I can honestly say training with JJ has been life-changing. With his help, motivation, and the occasional in-session counselling pep talk, I’ve lost a third of my body weight, built real muscle, and most importantly rebuilt my relationship with food and movement. I’ve become the kind of person who actually looks forward to working out and goes to the gym to feel good, not smaller. JJ’s sessions are always innovative, never boring, always purposeful, and sooo rewarding. He brings energy, skill, and genuine care into every single workout, meeting you exactly where you are while still pushing you to levels you didn’t think possible. The community he’s built is supportive and welcoming, and his programming makes consistency feel natural. If you’re wondering who to trust with your FINAL transformation, JJ is your guy. Couldn’t recommend him more.

5 /5 Vicky Bradford: I’ve been training with JJ for over 2 years. During that time I’ve lost over 3 stone, built strength and massively improved my overall wellbeing. When I first started, I was struggling with chronic back pain, couldn’t bend to tie my trainers and was in the physio twice a week. With JJ’s support, my pain levels are significantly more manageable, I feel stronger, am more resilient and only see the physio once every 6 weeks, if that. What I really value is JJ’s ability to know when to push me or when I need a bit more encouragement. Training with him has not only helped my physical health but it’s given me a real mental reset. It’s time when I can switch off from work and focus on myself. On top of this our sessions are fun. We have a good laugh, plenty of Arsenal chat, set the world to rights and it’s never a chore turning up. I also love that it’s a family run business. JJ and Amy make their clients feel like part of their extended family - in fact JJ trains my husband and kids so it’s a proper family affair for us. I’d highly recommend Leap Fit and JJ to anyone looking for a trainer that is super knowledgeable, supportive and genuinely invested in helping you reach your goals.

5 /5 Nicole K: JJ and the whole leap fit team are amazing! Leap Fit is such a great addition to the Dalston fitness scene. Great value PT sessions, high-energy classes, and really experienced and reliable instructors (including of course the legend: JJ himself!). Couldn’t recommend more! Don’t think - just sign up! You won’t regret it.
