It’s always a good idea, especially if you’re new to exercising or if your kid is new to exercising, to do a little bit of warm up and stretching, just to get the muscles going, just so you know that nothing is hurting or anything like that. Just so you know the limits of what you can do. Most coaches are starting kids with either Little League or soccer or even swimming, will have kids do, do some warm ups. But the important time is after exercise. The important time for injury prevention is after exercise and I’m seeing a lot more teams work with this, trying to get the kids to stretch.
