anatomy - describing thigh muscles, knee pain, and trying to push myself on the bike

[SteveO]

I get some knee pain when I push too high, too hard. The sprints? Hmm, that'd be my Mr. Obvious guess as well. You might also consider taking up yoga and some simple PT you can do at home while watching a movie or whatever...there are some great stretches and strengthening opportunities for those muscles around your knees, hips, lower back, etc. Stronger muscles can take some of the stress off the joints.

Knock on my head, er, wood, I haven't had any major knee issues to speak of since I took up a pretty intense yoga regimen a couple times a week the past 6 months. I also gave up indoor soccer. Which I miss.
