Often times during a workout you will find yourself with a muscle cramp. Some people will tell you to work through it and others to take a break. So, what should a person do when they find themselves cramping up? First of all, to avoid cramping, be sure you are warming up and cooling down when working out, you body needs to stretch and be ready for higher intensity workout moves. Also, be sure you are hydrated, but it probably isn't best to take large gulps of very cold water before or during a workout, that could actually make things a little worse. Once the cramping starts, stop the activity you are engaged in and begin to massage or slowly stretch the area that is cramping. Sometimes it may help to hold the cramped area in a extended position to alleviate the pain. These simple things should help when your muscles cramp, but if yours seems severe or very persistent, don't hesitate to check with a doctor. It never hurts and you never know. I am sure others here might have more to add about muscle cramping, these are just things that I have learned from experience.
