Who knew you could get sore stretching? It's a new experience for me. I've done 2 hours worth of yoga so far over my vacation. While I am more relaxed and loose now, I'm also sore. This is either a reflection of my tightening up since I haven't been very diligent about stretching over the last few months or maybe I just always go overboard trying to hold advanced versions of the asanas. Either way my hammies have been definitely feeling it over the past two days.
On another note, I've learned that I rock quite a bit doing fast pull ups. The pull up bar in my mom's gym doesn't have a very wide base and isn't bolted to the floor like it's supposed to be. I started rocking the entire structure while I was banging out a set of pull ups. I had to slow down my pull ups so I wouldn't tilt the entire bar structure over. I suppose I'm just too used to accelerating up since I'm usually trying to do muscle ups.
