This type of cross-training-workout-for-a-short-amount-of-time-until-you-feel-like-you-might-die is great for me. Occasionally. Like when I'm not hurt. When I can do this kind of thing, I just keep thinking about how it's only 7 minutes, and it makes it easier. Sort of.
I printed a few copies of this excellently illustrated Scienctific 7-Minute Workout from the New York Times to put around the house because somehow the cute illustrations make it seem less horrible to do. I haven't done it yet. I have done really similar workouts, but not lately. My back, while much improved (time and this book have been the key) isn't ready for this kind of stuff quite yet. But, Pete has done this and digs it. We both normally do a different circut that repeats 4 moves for 10 minute total, and this is more interesting because you only do one move for 30 seconds, resting 10 seconds in between. I actually am a little afraid to do this around him or the girls because I get into laughing fits when straining myself physically when I am not alone, and then I often get even more hurt.
I love the blue shoes this guy is wearing.
There's complete info in the link. Please don't get hurt if you try this. No one cares if you only do two moves or skip a bunch.
