I had to call a training time out on myself, today. Apparently my left leg is worse off than I thought. About half way through the second run I started to get a weird twinge in my calf and then a few seconds later my leg almost completely gave out on me.
I tried to push through for another 30 seconds or so, but the muscles in my leg were spasming pretty badly. I managed to finish the second set of squats, sit ups, and lunges, but had to stop during the third set. (I skipped the running portion.)
I’ll be trying to stay off my feet as much as possible tonight, and keeping a bottle of ibuprofen nearby. With luck I can complete tomorrow’s exercises at a slower pace.
