All you need to do is increase by 10 every 3 days .. You will really feel your ass the next day !!! AMAZING. Running doesn't do anything for your butt, just makes you more aware of the fact that it's wobbly!!!!
Do this routine before every shower: 50 jumping jacks, 5 pushups, 20 crunches, 20 mountain climbers, and 30 second plank. I like the idea of doing it before every shower, then it is easier to become part of a routine
