That use to happen to me a lot, but I haven’t felt that pain in a long time. I started doing yoga regularly which helps, but even without doing yoga, a lesson I learned from yoga prevents that situation in other cases. It’s about balance, so when you stretch your feet down, don’t stretch your feet down toe first, there is no balance there, stretch your legs down heel first, that way the back muscle is being pulled down and the front muscle is being pulled up with your toe, the two counteract each other and you will not get this cramping.

Seek balance in all things friends, including your muscles while you stretch.
