REST DAY to let the soreness in my calf muscles fully recover. I'm planning three days of training before the next event this Sunday, nothing too hard, mostly swimming.
I did some research on muscle cramps. Here's what endura.com has to say >>>
"Do you get muscle cramps? Magnesium is necessary for normal muscular contraction and relaxation. Low magnesium levels are associated with an increased incidence of muscle cramps, which can often be reversed with the addition of magnesium supplements. In one research trial, swimmers taking magnesium supplements during their training and competitions found an 86% reduction in muscle cramps. The reductions occurred after only three days of supplementation. If muscle cramps are an issue for you, adding some extra magnesium to your supplement regime is a must."
Guess I'll get a magnesium supplement, it's certainly worth a shot.
