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.
Prowler Sprint
Place your sled on an appropriate surface, loaded to a suitable weight. The sled should provide enough resistance to require effort, but not so heavy that you are significantly slowed down.
You may use the upright or the low handles for this exercise. Place your hands on the handles with your arms extended, leaning into the implement.
With good posture, drive through the ground with alternating, short steps. Move as fast as you can for a short distance.
