Sohail

"Working with Mohammad has honestly been one of the best choices I've made for myself. Before starting, I had trouble staying disciplined and didn't really know what I was doing, but he made everything feel simple and doable. He is extremely knowledgeable and actually take the time to explain what you're doing and why, which helped me build real confidence in the process. I've tried other places before, but this one genuinely stands out. I'm already a few months in, and the progress has been obvious. Not just to me but to the people around me too. The workouts are tailored, the support is consistent, and they genuinely care about helping you reach your goals. I feel stronger, more motivated, and finally on the right track. Highly recommend ATOFitness to anyone who wants real results and a trainer that actually pays attention. This has been a game changer for me."

"If you weren't familiar with what ATO stood for, it stands for Against The Odds and their name lives up to it. As someone who hasn't been able to exercise due to various health conditions I thought that it was impossible for me to lose weight and get fit, but Against the odds, they got me fit. Someone said they don't leave reviews often before and that's so true for me as well, I don't leave reviews often but that's how good these people are. If you want to look and feel the best you've ever looked and felt, give ATO a shot!"

"I don't leave google reviews often so when I do, it mean something. Training with Mohammad at ATO has been one of the best things I've done this year. I'm only a few months in and I'm already feeling lighter, more energetic, and in university people have been complimenting me back and forth. If you've felt stuck and you need a reset, these are the right guys for the job."

"Training at ATO is worlds apart from anything I've ever experienced in the past, they're honest and optimize their entire training regimen around reaching your goals. They even guarantee that you'll drop the weight so you aren't just paying them indefinitely without results. Overall 10/10 if you're thinking about training, this is the best place to do it."

Mohammad Saamir Junaid

"I honestly can't say enough good things about my sessions with Mohammad at ATO Fitness. He just has this real talent for knowing when to push you harder and when to crack a joke to keep the mood light. I found myself actually looking forward to our workouts, even on days I felt tired, because his positive energy is just so contagious. He helped me achieve things I never thought my body could do, and I left every session feeling stronger and more confident. 10/10, would highly recommend!"

"I had the pleasure of being trained by Mohammed, great person first off. He has the right mindset, he's kind and most of all in the gym environment it's all about discipline and motivation, and he makes sure you hold yourself accountable where he pushes you beyond your limits. He pushes me past my limits, showing me there's more than what my body has been capable of. If you want to lose weight, get jacked, and want to become your best self hit this guy up. I had a great time brother."
