Looking for some help regarding yoga. I've been doing Cathe's workouts exclusively for a few years now, along with running and walking. However, I'm feeling like I might need to shake things up a little to shock my body. What is a good workout to get? I checked out VF but I could spend all day reading the reviews! I figured Cathe fans will be able to help. I'm not really looking for a relaxation style, I'm more interested in something that can replace a strength day. I'd rather have something in the intermediate category so that I can work up to conquering the whole thing. Maybe I'd be better off trying a class first? Thanks in advance!:7
