EXCELLENT Based on 74 reviews Posted on IvayloTrustindex verifies that the original source of the review is Google. I trained with Zack Fitness in Fitzrovia, London and honestly I couldn’t be happier with the experience. From the first session, everything felt very professional and structured. Zack really takes the time to understand your goals and builds a plan that actually works for your body, not just a generic program. What I liked most is that every session had a clear purpose. It wasn’t just random exercises — everything was focused on improving strength, losing fat, and getting real results. He pushes you in the right way but still makes sure your form and technique are always on point. After a few weeks training with him, I already felt stronger, more confident, and could see visible changes in my body. Zack is not just a personal trainer, he really cares about your progress and keeps you accountable. You can tell he has a lot of experience and knows exactly what he’s doing. If you’re looking for a personal trainer in Fitzrovia or Central London, I highly recommend Zack Fitness. One of the best decisions I made.Posted on Chandra VermaTrustindex verifies that the original source of the review is Google.
