The 8 Best Stretches to Do Before Running | Nothing can derail your fitness goals like an injury. Running with muscles that are cold and not properly stretched can result in a muscle strain that keeps you off your feet -- and off the road or trail -- for days, weeks or even months. Beginning each running workout with a 5- to 10-minute jog followed by stretching helps warm up your muscles sufficiently so they’re primed for your run, whether it’s a couple of miles or a marathon.

Got knee pain? You probably need to work on your ankles. Over time, especially if you spend a lot of time sitting, your ankles lose range of motion—which forces your knees to compensate (and complain). Do this move as part of your warm-up, or anytime you like. You'll see the benefits in your walk, run, or strength workout almost immediately.
