Trustindex verifies that the original source of the review is Google. Had a 2 week experience in Redefine when over from UK. We were given a great welcome and encouragement. Targeted personal training for knee improvement was very professionally delivered - but always with a personal touch and empathy. Well done Kyle and Hannah! And thanks!Posted on Brian BrianTrustindex verifies that the original source of the review is Google. Kyle And Kolja Are The Best Trainers I highly recommend themPosted on Jameson KonenTrustindex verifies that the original source of the review is Google. Redefine Fitness in Stony Brook is hands down one of the best gyms I’ve ever been to. The atmosphere is welcoming, the equipment is top-notch, and the whole place is always clean and well-organized. But what really makes it stand out is the staff. Shoutout to Both Kyle and Kolja. They are incredibly knowledgeable and genuinely care about helping you reach your goals. Whether it's tweaking your form, answering questions, or just offering that extra bit of motivation, they’re always professional and approachable. They know what they're doing, and they make you feel confident and supported.Posted on Chris RuedTrustindex verifies that the original source of the review is Google. awesome trainers! everyones great!!Posted on Sarah ArrietaTrustindex verifies that the original source of the review is Google. I previously posted a positive review for my former Redefine trainer, Amanda. Now that she is in management and I have a new trainer, Hanna, it’s time I sang her praises! I continue to be proud of myself for making the commitment to working out. This level of exercise and strength training has been the best gift I could ever give myself. I feel strong, sure-footed, and healthy. I couldn’t do it though without Hanna! She might be young but she’s wise and sensible. We have such a nice rapport that I never hesitate to tell her if I’ve got some little issue troubling me because I know she will find a way to adapt my workouts accordingly. This is wonderful because it means that even if I’m not feeling 100% for some reason, most recently from jet lag, I can still get a good workout in. Most days I feel great and we get to it! Hanna pushes me, just the right amount. And all the other trainers are so friendly, my little successes are often met with cheers from the entire staff. It’s really sweet, like all of Redefine is cheering for my success! With this level of support from Hanna and the Redefine family, I know I will be a client for what I hope will be a very long, healthy life!Posted on Lisa BlakeTrustindex verifies that the original source of the review is Google. Been training here for over 2yrs and it’s been great. The trainers are knowledgeable and polite they’ve helped me work through past injuries. And the new faculty is nice and well equipped.Posted on V R
