Hi, I'm Christine King. Let's talk about cramps in the buttocks from lunges. This most likely happens from overdoing it the first few times you practice lunges, overuse of the muscle can cause cramps as well as dehydration. So during any exercise program you do want to make sure you are drinking water. But there are ways to alleviate some of that cramping. First take a day of rest in between working the lunges. Secondly, you want to stretch the muscles that you use during the lunge work so that you lengthen the muscle and the connective tissue. That will also help to lessen the cramps. For example, lying on your back on your bed or on a mat, you want to bring the right knee into the right shoulder and just gently stretch the knee into the shoulder to toleration until you feel a stretch in the buttocks. Hold the stretch for about 15 to 20 seconds. Then take that right knee and angle it off to the left shoulder so you are on a diagonal. You will feel that more on the outside of the thigh but still in the buttocks. Repeat those on the left side and then bring both knees into the chest, stretching all throughout the buttocks and the low back. And finally, a great crossover stretch would be with the left leg out straight, crossing the right knee over the left leg and using your left hand to push the knee across the body.
