Instructions
90/90 Hamstring
Lie on your back, with one leg extended straight out.
With the other leg, bend the hip and knee to 90 degrees. You may brace your leg with your hands if necessary. This will be your starting position.
Extend your leg straight into the air, pausing briefly at the top. Return the leg to the starting position.
Repeat for 10-20 repetitions, and then switch to the other leg.
Stiff-Legged Barbell Deadlift
Grasp a bar using an overhand grip (palms facing down). You may need some wrist wraps if using a significant amount of weight.
Stand with your torso straight and your legs spaced using a shoulder width or narrower stance. The knees should be slightly bent. This is your starting position.
Keeping the knees stationary, lower the barbell to over the top of your feet by bending at the hips while keeping your back straight. Keep moving forward as if you were going to pick something from the floor until you feel a stretch on the hamstrings. Inhale as you perform this movement.
Start bringing your torso up straight again by extending your hips until you are back at the starting position. Exhale as you perform this movement.
Repeat for the recommended amount of repetitions.
