Mike has been amazing to train with and I’ve been pushed out of my comfort zone to do more than I ever thought I could do. Transfitnation has given me a sense of accomplishment and I feel so much better physically and mentally since starting. Highly recommend!!

I highly recommend Transfitnation for anyone wanting to work on their fitness. The one-on-one attention in a private setting has been the perfect place to help me work on/reach/evolve my fitness goals. I've gone from sweating bullets doing 5 pushups inclined on stairs to doing 15-20 Bosu pushups as a warmup. My trainer Stephan is always well prepared and motivating during our sessions, as well has preparing at-home workouts for me to do on days he doesn't see me. I've also worked out with most of the other trainers on the team when scheduling necessitated, and all have been great and had access to Stephan's notes to keep everything as consistent as possible. The physical space is well equipped and kept immaculate. Again, highly recommend.

I started training at Transfitnation since the beginning of 2022. I had injuries with tendonitis and jogging in the past. I stopped running for years because of it. Their knowledge not only help me build up muscles I need to protect my joints, but also continue to grow stronger without more potential hurts or pain. Highly recommend their services if you want to grow stronger without injuries. Revised 10/17/23 Here is an update: I have transitioned from group class to private coaching with Stephan, tendonitis and pain is less and less of an issue. I am clearly stronger then last year. My muscle strength enabled me to take up wind surfing, Thai boxing and running, sports I’ve always wanted to do without worrying about injuries any more. This is one of the best investments I do for myself.
