Hi! I had leg cramps so started on Magnesium and they have pretty much gone away. My daily routine includes a 30 min exercise routine in the AM (EssentricsTV) and a 30-50 min walk each night. If I don’t do those and am too sedentary (I love to sew!) then I would get leg cramps. When that happened, I would do some leg exercises in bed or on the worst nights get up and walk around the house which seemed to calm down my legs.
FYI - I started taking calcium and vitamin D supplements for osteoporosis at the same time as the Magnesuim just so you know the whole story! Good luck to you!
