For anyone who wants an easy, fun, relaxing excersize, i say pull out the bike! You know.. that thing in the back of your garage that has two wheels! Yeah that thing! I just got reintroduced to mine, myself! I find, after biking for a few minutes i dont want to pull back into the house. It's awesome and it gives me time to think.
Another thing I like to do is dance. Pull out the Poison or Motley Crue and go to town. I dance for a good 20 minutes. That biking and a few crunches is my work out.
