So after chatting w/usmccds in another thread and wandering into a discussion of Bikram Yoga, I just wanted to start a little thread here.
Disclaimer: I am not any sort of certified expert in yoga or strength training. Just a guy that does some of each.
Brief background: I'm 5-11, about 210 pounds, 28 years old. I played sports all my life and had a decent career as a small-college football player, then ran marathons for a few years before coming back around to mostly strength work. Predictably, the long period of heavy lifting, football, and then hardcore distance running turned me into a mess of sore ankles, knees, etc. I always had very poor flexibility, mobility, and balance.
About five years ago, I wandered into Bikram yoga studio, courtesy of a Groupon that offered unlimited yoga for two months for like 20 bucks. I have maintained a steady practice most of the intervening time, depending on how much I happened to be running, lifting, or biking at the time.
It's the same 26 postures in every class (twice each)
It's 90 minutes long every time
It's in a room heated to 105 degrees
I find it a very enjoyable "active recovery day" between hard lifting and/or running workouts. I don't always feel good going INTO the room, but I always feel good when I leave. Sort of a "pleasantly drained" feeling - I sweated a lot and got a bit of a workout, but I feel pretty refreshed.
Re: usmc's question about whether it's harmful to dehydrate yourself...I do sweat a ton (5-7 pounds, probably) but no more than I would in a hard wrestling practice or a long and tough lifting workout on a hot and humid summer day. As long as you're wise about going to class fairly well-hydrated (NOT HUNG OVER) and/or you make sure to sip on some fluids for the rest of the day after you go, that's never been a major issue to me.
Anyone interested, ask away.
