I'm Greg McLean. I'm going to show you how to do hamstring pull-ups. One of the best reasons for doing a hamstring pull-up is there's not a lot of different ways to train the hamstrings and it's a very hard exercise. So as far as really strengthening the legs and throwing something different at the body it's a great exercise. Now if you don't have a partner one of the best things you can do is use a squat rack like we're going to use here today. You want to use a 45 pound bar and put 45 pound plates on each side. You want to put the bar on the inside of the rack and it should pull up against the rack nice and snug. That way when we are going to do the exercise, it's going to help us to kind of hold the body in place. On this exercise we want to start with the feet underneath the bar. We want to make sure knees and feet are about shoulder distance apart. On this exercise we're going to keep the hands in nice and tight to the chest so we want to imagine we are squeezing a grapefruit between the elbows and the back. This is going to ensure that we keep a nice flat back and we force the hamstrings to do the work and take some of the stress off the back. We want to imagine we have a ruler from the top of our head down to the coccyx to ensure that as we come down my back is not rounding. What ends up happening on this is I want to come down nice and slow and as I go down lower and lower when it gets challenging for my hamstrings, they're going to give out. As a result we don't want to fall down so we're going to put our arms out, kind of push ourselves back up and then as we get to the point where we can engage our hamstrings again we want to do the rest of the pulling with those hamstrings. So the point of this exercise is using the hamstrings as much as we can as we fall and then using the hands as little as possible to absorb the stress and then to push back up. So we're using those hamstrings, getting a great workout.
