One of my favorite ways to start the day is bouncing on a mini-trampoline outside in the morning sunshine.
An additional option for parents is to involve your kids in this activity.
I get some of my favorite tv shows (Friends, Sex and the City, Bones, etc.) on DVD (usually from Netflix) and ONLY allow myself to watch an episode if I'm working out! Plus, it helps the 45 minutes to an hour go very fast!
