For a few months there I was doing 2 hour marathon work outs, really taking my time. But I changed about 1 month ago to doing more intense workouts. I take little time between sets, and I try to make my muscles burn as much as I can take. I do this fairly often, but it had been awhile since I had done legs, particularly calves like this. I will eat some coconut flesh, honey, and papaya or strawberries 10-20 mins before a workout. But I've never really had any problem before. I did eat a cooked steak (at a banquet) right around the same time it started seizing up. I mean, it was already starting to get sore, but it happened almost simultaneously as I ate the steak, so it's hard for me to blame the cooked meat - though maybe.
My calf is starting to release today. I think maybe I just hurt it that much in the gym.
As an aside note, something interesting happened last night. I started getting some pretty bad diahrrea, sorry if you don't want to hear about this. Anyways, I drank coconut water, and apple cider vinegar, and at lemons/limes like I usually do when this sort of thing happens - I tend to want to eat those. Towards the end of the evening I got hungry for steak, which I ate, but of course it mostly moved right through me. So anyways, I figured I'd wake up w/ less muscle b/c of it, but not the case. Woke up this morning, I had actually gained some muscle overnight, while losing waist size. I couldn't hardly believe it.
I think I'm gonna start eating fewer big meals a day. I think maybe I spend alot of energy on digestion, and since I had nothing in my stomach to digest, that my body had time to repair? I tend to eat close to bedtime too, I think that's maybe a mistake. Body probably has a harder time digesting while lying down, and less energy to devote to repair, as it's being used for digestion.
