  • I love Transfination. It is honestly the best decision I ever made. I feel physically and mentally stronger each day. I truly have the best trainers and support system; shout out to Sterling and Steve who are just amazing at what they do. I used to dread going to my local gym, and now I look forward to working out thanks to this team at Transfitnation.I used to suffer from constant chronic back pain, which has now subsided thanks to the stretching and work outs.Look no more, this is the place to be. Check them out, you will not regret it.

  • I've been training with Steve for about 2 years thru Transfitnation- remotely since Covid, via Skype and the Transfitnation App. What I like the most is that Steve is attentive to my needs, limitations (both my physical limitations and my age - I'm a senior citizen ) and takes a personal interest in my development. His workouts are designed to target my weak areas and increase my flexibility after years of sitting at a desk on a computer. The workouts are custom designed and the exercises are varied so that you aren't performing the same routines. In addition Steve has monitored and mentored me on eating habits and the importance of combining proper eating habits and strength training to achieve my goals. Steve is very professional and personable. He exerts the right amount of encouragement during workouts without being obnoxious (as some trainers can be), but still pushes me to reach my maximum effort. Our Skype sessions start off with a recap of what I've done since our last "in person" training including workouts, eating trends/weight goals, and physical issues and a discussion of how to overcome any shortfalls or issues. I highly recommend Steve and Transfitnation to everyone of any age group.

  • Positive: Communication ,  Professionalism ,  Quality After giving birth and gaining alot of weight during my pregnancy I could not wait to get back in shape. Finding the right gym and trainer was very important to me. I found the perfect gym and trainers here! They personalize the workout to each client. I highly recommend them.

  • It is with great pleasure I write this review about Transfitnation. I started feeling very weak and out of shape. Their persistence has kept me focused and committed on my personal growth. They have provided great guidance not only in my strength but in my nutritional habits. Their personal training sessions has kept me progressing consistently and the results have been fantastic.

  • I was seeking a personal trainer after gaining weight and very little exercise during the pandemic lockdown. I did not want the typical “gym” experience since I was injured in the past while using an inexperienced trainer, with a one-size-fits-all approach. I found Transfitnation online and went for a free consultation. I signed up for three days per week and have been working with Steve or Julien since January 1st. I lost the weight I had gained and, equally important, gained strength and balance. My workout was customized for me and in 4 months have not had any pain in my shoulder and lower back which were typically weak spots. Steve and Julien are professional, competent and friendly. It is a no-judgement zone. My daughter has also joined and sees a benefit when competing in sports. I am very happy with my results and signed up for additional months.
