First off, let me say I feel great and I'm losing weight.

I walk everyday for an hour. I also go to the pool and swim lenghts 6 days a week, 1 hour, but I'm not pushing it, I swim slow. 2 lengths breathstroke, 2 lengths front crawl. So, it's another 22 minutes to walk there and back.

I'm thinking, this should be ok as Mark talks about moving slowly ALOT.

Is there something I maybe should be taken so I don't lose lean muscle? Or is that only for when you do really hard exercise?

Thanks in advance.
