I wear these shorts when playing basketball and practicing tae kwon do. I have very tight hips and it takes forever for me to warm up normally to where I can do kicks and forms to my satisfaction, even with regular stretching.These shorts help with keeping muscles warm and loose so that period of loosening is much shorter. When I wear them my muscles are already relaxing and warm as I drive to my various activities and I'm ready to stretch.Less hip pain and more focus on what I actually want to do.They would be good for most any physical activity.They do have some pockets that would be useful for runners to keep keys or phones.So a lot of things to like with these shorts.
