"Working with Momentum has been transformational for both my mental and physical health. I'm eating better, more active and overall, I have more energy to get me through the day and week."

Ken Grunke

"I was a runner in my 20’s and 30’s but gained a bit of weight and running became difficult. Through Momentum’s guidance I was able to lose nearly 60lbs and run again. The classes and nutrition advice is what helped me get there. I even ran my first 15k race and am shooting for my first half marathon at age 58!"

Mark V.

"Not only has Momentum’s program changed my body, but my lifestyle. I’ve learned not to stop snacking but to snack sensibly with healthy options. The daily motivation that is provided keeps me inspired to come to classes at least 3 times per week after going through one on one personal training for 3 months and losing nearly 30lbs!"
