Hot yoga is becoming more popular every day but there is a lot of conflicting information regarding benefits versus injuries. Most of the information does not quote sources and is therefore is difficult to follow up on. It has unquestionably helped me become a more flexible person but there is a lot of information on the net regarding horrific injuries including slipped discs, muscle tears, neck injuries, emotional problems, and even strokes. Is there a research-based, or at least a factual breakdown on the health benefits of stretching at temperatures above body temperature versus the injury risk of exercising at temperatures above body temperature?

I'm an athlete, and about a year ago, I purchased one of those ab rollers. One time, I was going through the motions and I experienced an orgasm. Now, it happens about every time I use it. I thought it was extremely weird, but then read where women experience orgasms through lots of things. I was just wondering how it is possible for those feelings to happen just by working out my abs. Also, what are some other weird ways that women have had orgasms? Thanks so much.

I wanted to know how many days of rest is recommended between workouts. I heard it was three days on to one day off...is this enough? I workout on a treadmill for 50 minutes every day and have for the last 14 months. I was not aware of how rest played a very important role until I recently read a brief article on it. I guess my question is, do I need to take that day of rest and how important is it?

A friend of mine bought me a month's worth of yoga classes over the summer. I loved it! I've never found an exercise/fitness regimen that I actually WANTED to stick with. It helped with a lot of my long-standing physical issues (balance, back pain, stress, fatigue) and was a perfect balance of stretching and strengthening for my fitness goals. The only problem is that now that my month is over... I can't really afford to do it anymore. I've looked all around for inexpensive and conveniently located studios, but I can't find anything that's in my price range or fits in my schedule. What resources are there for broke aspiring yogis? Are there any guidelines for practicing yoga at home? Are there any exercise routines that are similar to yoga (i.e., low impact, stretching + strengthening) that are less expensive or easier to do without an instructor?

I know there are video games out there now that require you to move more, unlike traditional video games. Are these games, like Wii Fit, a good way to be more active or are they doing more harm than good?
