Help with hamstring cramps

I've heard all sorts of causes for cramps, sort of like all the different methods people suggest to cure hiccups. Calcium deficiency, water deficiency, sodium deficiency, the muscle is too weak compared to the opposing muscle, etc.

I get pretty bad foot cramps, and the calcium method seems to have helped some. I snack on string cheese for extra calcium and also take calcium gummies if necessary.

If the muscle is too weak, you could try doing some deadlifts. It doesn't have to be heavy weight at all.
