I have tried working out consistently my whole life and have never been able to do it. This is the first time I’ve gone into a workout knowing I’m going to succeed, and I love the workouts. There’s no more excuses when the workouts aren’t time consuming. Loving the burn!

I haven’t missed any days of exercise since I started and am actually able to do a few push ups on the floor.

I tried to incorporate the P90X program into my training schedule and was successful for a few months, but my DVDs are now getting dusty. I was grateful to find the 20 Second Fitness program. The high-intensity, burn-em-out approach is an awesome way to start my day. It is so fun to be getting stronger and faster!
Scott , via Email
I am down 10 lbs to 183! Eating better and working out regularly. Spencer is right, the burn from 20 Second Fitness stays with you all day. I am lending the intro week and week 2 to my brother for him to give it a go.
