I am in the gym 5 days a week which include 3 days of 40mins cardio and the other 2 days of moderate to heavy weight training. I also do an aerobic class on Sundays for an hour which also include light weight training. My concern is how do I develop stronger and shapelier hamstrings?
For great hamstrings I suggest the following exericises:
Leg Curl
Lay face down on the leg curl machine with the pad just below your heals. Curl your feet towards your butt and squeeze your hamstrings and hold in the contracted position for a count of 2 and then slowly release back to the starting position and repeat for 8 to 12 reps.
Stiff Leg Deadlift
Start with the barbell on the floor, against your shins, bend down and grab and stand up then while keeping your legs and back straight, lower the bar toward the ground until you feel a good stretch in your hamstrings, slowly stand back up and repeat for 10 to 15 reps.
