I actually have been switching and going backwards already... works out the back sides of my butt if I focus and tighten when I do it

I wanna have a nice looking tush in those skinny jeans someday
Thank you so much for the idea of switching back and forth at ever song... I have just been a clock watcher, but the music sounds much more fun!
I wanted to get the precor, but they were just to much money and I just couldn't afford it right now. Maybe if I wear this one out I can get one of those in the future
