Can do most exercises at home in 15 minutes. As a busy mom working full time, sometimes this is all I have the time or energy for! Great option for those days Im just too tired to make it to the gym. The only flaw, I dont have a pull up bar to do the pull-ups so I improvise on that part with different exercises.
