Push-ups and Yoga

How many push-ups can you do?
I can proudly say I did 67 non-stop.
Does anyone use the 100 Push-ups App on their iTouch? It's really useful to help build up arm strength.

Does anyone do yoga?
I know it sounds weird for a guy to do yoga, or so say my friends, but I find yoga a lot more challenging than what it originally seemed like.
I tried it out yesterday and I had quite a difficult time finishing the first 7 minutes of the instructional video. It really works out the muscles in your body that you don't use often.
Here's a link to anyone who is interesting in trying out yoga, its fun and don't be discourage by the fact that it looks weird.
