Tip of the Day:
YOU DESERVE A BREAK! Even pro athletes take one day a week to let their muscles recuperate (some take a whole season off, although we don't recommend that). So, in case your enthusiasm has gotten the better of you, make sure to take a full day off each week of both cardiovascular and strength-training activities. Stretching on that day is fine, as long as you don't actually work your muscles. This will allow your body to recharge for Week 2.
