What people are saying about NuActive Fitness:

I had my first session this past weekend and I loved it. Very focused instructions. A little sore today but it feels so good. I’m not a gym person but I’m a runner and now I know I am being trained to work on other necessary muscle groups. Loved it!
— John M.

Loved T! Great motivation! Pushed me through the days that I did not feel like working out - almost every time :). I have been training at home for 3 months now and have so much more strength and energy and lost 7 lbs! I actually have muscles now that have replaced the jiggly fat. I also like the exercises, never boring. I would recommend to anyone.
— Catherine M.

— David A.

The 7 months that I have been training with Tsveti Kern and Nuactive Fitness have truly been some of the best and most eye opening months of my life. I have learned so much about the world of fitness, and have even gained a lot of well-needed confidence.
Tsveti is an amazing trainer who cares deeply for her clients. She pushes her clients to overcome their limits while tailoring exercises to their unique ability level. She is attentive to if an exercise is too easy or too difficult, and accommodates accordingly. She also always comes up with new, fresh exercises to do as the capability levels of her clients increase. Tsveti even coaches and gives advice on the importance of proper nutrition, of which is vital to getting maximum results.
Personally, I have overcome challenges I never thought possible. Tsveti has helped me to increase my endurance while running, enough to tackle a 5K. In addition, I am now able to do full body push ups, of which I had only dreamed of being able to do in the past. I notice a drastic difference in my clothing, I have even dropped down a few sizes. This was especially noticeable in my prom dress, of which wouldn’t have fit as beautifully without Tsveti’s training and expertise.
You will not regret signing up to train with Tsveti and Nuactive Fitness. Get ready to reach your goals, get motivated, and get in the best shape of your life!
