Hi, this is Jamie Glick. I'm here to talk about how to enhance your flexibility. One of the goals you should have in your fitness program is to become strong, but being flexible can help you keep injuries at bay. The static stretch, which I'll demonstrate for the hamstring, is one that's going to be held for 30 seconds. So, for this stretch, I'm going to prop my foot up on a small step stool. My back is going to remain straight, and I'm going to lean forward, bringing my bellybutton toward my big toe. Keep the back straight, and that should be enough. Once I start to feel that stretch, I'm going to hold 30 seconds. The second way to enhance your flexibility is through a dynamic stretch. So, for the hamstring, you're going to lay down, put one leg flat, one leg up. And, this is a dynamic lift. And, hold for two seconds, and then back down. So, lift, hold for two seconds, back down. Lift, hold for two seconds, back down. And, you're going to repeat this one for 10 repetitions, two seconds each.
