I haven't worked out since I had DD... sigh.
Hopefully there will be some changes soon allowing me some time to get back into it.
I'm a strength training freak. I am a certified trainer and used to teach boxing circuit, cardio kickboxing and a few other types of classes.
But...
I love love love LOVE David Kirsch. His programs are so effective and engaging. I get results in two weeks with his New York Body Plan and his maintenance programs are pretty easy to follow, yet intense.
It's great... a whole workout with a balance ball, 5lb dumbells and a medicine ball... heck, you can even skip the medicine ball if you want and just hold the dumbells together.
Love love love him.
