When you can't make it to the gym or out to run because of weather, do something indoors. Jill is doing a step video. I did the following, and if you need an exercise, give this one a try. 100 push ups 100 sit ups 100 squats
Do them in sets and set a time goal and try to beat it. I did it in 15:41. Setting time goal keeps you moving (you can take 30 second to minute breaks) and from lollygagging.
This workout is "Crossfit" like. It uses what you have--your body and a room--but it's one of the really basic routines that is done in Crossfit. I'm not a member of Crossfit but appreciate what they do and how they helped me get back into more practical and full body workouts. They have a special going on now if you're in Tulsa and interested. http://www.nextgenerationcrossfit.com/
