No, I didn't pull it riding.

Two weeks ago, pulled my right hammy rounding third in a recreational softball league.

Tonight, I'm worried about the right one, and I pull the left sprinting to second on a grounder. I actually heard a pop on this one today. Just finished icing it for an hour or so. I couldn't tell you what grade of strain it is...not bad enough that a a visit to the dr is in order. Can't straighten it, and if I walk on it wrong it kind of collapses under me.

So, several questions come to mind.

Why am I pulling hamstrings so easily? My legs are in pretty decent shape, but not tiny. I'm a clyde and they're pretty much entirely muscle. Am I just not stretching and warming up adequately? I gotta admit I've been bad about daily stretching lately, and I can feel my muscles tightening up. How can I avoid this in the future.

What's my best approach for healing this thing up as quickly a possible?

Is biking helpful or harmful for a hamstring injury? Last time I skipped a day of riding, but was back on two days later. Riding doesn't seem to hit my hamstrings too hard, so I had no problem with some moderate riding. I'll probably try to ride on Friday. But does cycling cause any issues with hamstrings?

Thanks, for any info you can provide or point me to.
