Donna Wilkinson: Now, its time to work on our hamstrings. This is a very dynamic exercise, will also work your balance and your core strength. Basically let me show from this side what we want to have. We want to have one leg stay straight. This is the hamstring we are working on. The other leg is going to kick straight back, as we go down, touch the floor with the control and then come back up, using the muscles and the strength in your hamstring. So, we are going to do this walking forward and in a variation if you want to make it more challenging is just turn around and walk backwards. Here we go. Nice and control going down, really get that back leg to kick. Make sure you keep your body nice and arched; you dont want your back to hunt you over, so keep your body nice and straight as we are doing this. Come back up, opposite leg. Really feel that stretch going on the back of the hamstrings as you are kicking and pulling back up. So, if we want to make it a little bit more difficult, we just turn around backwards, same thing. Really kick that leg back. Really feel that stretch in the back of the hamstring. So, couple of different variations you can do with this, but you really should feel nice and tight in those hamstrings and that lower butt really getting that area nice and firm.
