I'm Ashley Mitchell and these are exercises for weak hamstrings. It's important to strengthen those hamstrings because every movement that you do push or pull, walking or whatever it may be involves your legs which involves your hamstrings. So a great exercise to strengthen those weak hamstring muscles is not only to work out the hamstrings but also your hip extensors. So for example a deadlift, weights of your choice right in front of you to take it down, looking up the entire time, shoulders are retracted, your chest is up and out, your abs are engaged. You have a nice arch going on with your back, your knees are locked doing this for about 12 to 15 reps, three to four sets, always maintaining your form. So what most people don't realize is they also need to involve their glute maximus muscles to strengthen their hamstrings. So for example your hands are right below your shoulders to crunch your knee to your chest to fully extend up, really getting a nice workout with your glute maximus and your hamstring muscles, always maintaining form, fully elongating your leg when you take it out, getting a nice little ab crunch, taking it in and you want to always think about your form. You want to be doing about 12 to 15 reps, three to four sets, a few times a week. Have fun with it.
