"I worked with Osman at the South End site for 6 months from last October through this March. I had a wonderful experience with him -- so much so that I intend to sign up again soon. I am an older man who has never done anything like this before and Osman hit a really effective combination of encouraging me to push myself while respecting some of my physical limitations. I felt pushed in a positive way, and I feel like it worked really well for me. In addition everyone else on the team was really friendly, positive, and encouraging!"
"I have been working with Jet trainers for three years. All of the trainers I have worked with are extremely knowledgeable, professional, and clearly understand my goals. The team is very welcoming and friendly too. They take an all-encompassing approach to health including nutrition and meal planning. I always feel challenged in my workouts and I have seen fantastic results"
"I've been training at JET for a year and a half now and I can't say enough good things about my experience. First of all, Shubha is AMAZING. She just knows her stuff and has helped me to become stronger and more aware of my body. I love how Powerhouse Pilates allows me to focus on building strength AND flexibility. Plus she's just a fantastic person - kind, funny and caring. I've never been someone who enjoys working out, ever, but I find myself looking forward to our sessions and getting up twice a week to work out at 6 AM. But I think the best part of JET is the sense of community they foster. From the minute you walk in the door you feel welcomed. It's just a great vibe. The gym/personal training experience can feel very transactional, but I always leave JET feeling like I just hung out with some friends and the workout flies by. I can't recommend them enough!"
"JET has been the best experience I’ve ever had at a gym. Shubha is smart, kind, and extremely good at her craft. I’d love to see powerhouse Pilates expand even more and I hope I’m always able to work with Shubha!!"
"This gym has truly been a game-changer for me, and I owe a huge part of my progress to my phenomenal personal trainer, Dani! Her expertise, encouragement, and personalized approach have been instrumental in my journey towards a pain-free and healthier lifestyle. Dani's dedication and passion for what she does shine through in every session, making each workout not only effective but also enjoyable. The entire team of personal trainers here is incredibly friendly and welcoming, creating a supportive atmosphere that motivates you to push your limits and achieve your goals. I highly recommend this gym to anyone looking for professional guidance and a positive fitness environment!"
