Do you take the time to stretch? Do you know how to properly stretch before and after a workout? The American Council on Exercise offers these stretching recommendations: breathe in deeply, then slowly exhale as you stretch the desired muscle to tension; hold the stretch for up to 30 seconds, then relax and repeat the stretch a few more times; when holding a stretch, move as little as possible, which can help prevent you from injuring yourself; don’t stretch a muscle that isn’t properly warmed up; and don’t stretch a muscle to the point that it becomes painful.
