OK, I've got these step things - well actually they're Kerry's and I'm borrowing them. Can I go ahead and tell you that I stepped up and down on them for 20-minutes on Monday (alternating legs and doing upper body free weights after 20 steps on each leg) - and I literally could not walk on Tuesday. For real. I'm thinking it worked. Oh my goodness...my calves, butt, quads, inner thighs, outter thighs. Who knew stepping up and down on a couple of steps would do that? Um...apparently not me. Chris has been walking around the house saying "mommy needs to learn moderation". I did it again this morning...but just used one step. Still got the burn, but maybe I'll be able to walk tomorrow.
So, if you're looking to reduce the size of any of the parts I listed above - I'm recommending a step.
