Dr. Bruce Dan: Simple exercises to stretch out your calves, your thighs and your hamstrings can prevent cramping. Stretch before and after you work out and don’t forget to add a five-minute cool down period of moderate activity like some unhurried walking to your routine. Also, heavy exercise can cause the body to lose potassium. Foods that are rich in potassium, like bananas, can prevent leg pains. Remember to drink enough water, at least eight 8-ounce glasses a day are recommended to prevent dehydration, which can cause leg cramps. The most important thing may be to slow down a little. When people start an exercise program they sometimes go overboard trying to whip themselves into shape. But that’s exactly the wrong approach. Instead, increase your pace gradually over the first three months. When it comes to fitness, slow and steady wins the race.
