Hi all!
I've been lurking here since starting the program, and have really enjoyed the posts and learned a lot. I do have a question, though...
Last night, I was telling my husband about my routine and he expressed concern over the step-ups, saying he thinks I may damage my knees over the long haul. Now, he's not an exerciser by any means, strong from his job but not fit, y'know?
So I thought I'd run this by Those Who Know.
I'm 5' 4" tall, short-waisted with long legs for my height. Since the beginning of the program, I've done the step-ups on a Reebok Club step, with six risers under each end. (Do you say, "Six risers" for that, or 12?? I never know how to state a pair of db weights like that, either.

)
I started out with body-weight, working up till yesterday's workout (A-7) where I was using 20# dbs in each hand. This was tough-- I was literally grunting out each rep, but keeping my form, so I felt the weight was about right. I felt a bit of a twinge in my left anterior tibialis towards the end, but nothing alarming.
Today, I'm fine, nothing but the vaguest of soreness in my muscles and no knee upset. Soooo.... am I in danger of wearing out my knees, or should I just smile and nod at the DH and go on doing the workouts as I have been?
Also, I'm having trouble with pushups. I can't seem to go down past the point where my upper arms are parallel to the floor, even doing them on my knees, it's tough to break parallel. It feels like something "catches" or binds in the area between my shoulder joint and my chest, right at the tops of my arm pits, if that makes any sense.
Does anyone know how to get past this problem? I feel like such a weenie, doing the cable rows and then doing half-ROM girlie pushups on my knees! LOL
(Just fyi: My other weights in that workout were: squats, 70#; cable rows, 140#)
Thanks for your advice and patience with a newb!
