I did the 3-mile WATP w/hand weights this morning.

I've done some sort of WATP every single day for the last 3 weeks, and I'm wondering if doing them every day without a break is hurting rather than helping. I am trying to switch it up (weights one day, abs with the belt one day, walk/jog one day), but my weight loss progress has really slowed down the last couple of weeks and I'm wondering if that might be part of it.
