tl;dr - Haven't exercised in 10 years, ran a mile yesterday, not SUPER sore, but left leg is more sore than the left; am I injured? Can I run tomorrow even if I'm still kind of sore?
Longer version:
When I was 18, I was in great shape: I was a gymnast with a fair amount of muscle, I could run a 5:00 mile, I felt great all the time, and I was never sore for more than 24 hours.
That was 10 years ago. I haven't done ANY exercise since then. I haven't gained weight due to my metabolism being off the charts, and I'm still surprisingly fit-LOOKING. I decided I wanted to get back into shape yesterday, so I went for a run because cardio was always really easy for me. 1 mile, about 8 minutes. Didn't really push myself, could've gone a lot faster, wasn't sweating or even out of breath, but my fucking calves were killing me afterwards.
It's been about 24 hours now, and my right leg is almost completely fine, but my left calf is still pretty darn stiff. Not to the point where I can't walk around or anything, but I am getting a little bit of pain walking up the steps and stuff.
I'm wondering if perhaps I injured myself, or maybe my left leg is just that much shittier than my right leg (I did have a pretty right-leg-heavy physical job for the last few years, as weird as that sounds.) I'm hoping it'll feel better tomorrow, and if that's the case, should I try running again? Maybe a shorter run? Or start at a slower pace and see how it feels during the run?
Thanks!
