Question: Should I Stretch Before or After I Warm Up?
"I've heard you should stretch before you run. What is the best time to stretch -- before or after warming-up?"
Always warm up
before you stretch. It's a bad idea to stretch cold muscles. If your muscles aren't loosened up before you stretch, you're more at risk for pulling them.
Do about 5 to 10 minutes of light aerobic exercise to loosen up your muscles and warm you up for your run. Try walking briskly, jogging slowly, or cycling on a stationary bike. Make sure you don't rush your warm-up.
