• Start 10 yards away from sled

• Perform Duck Walk—walking crouched down with hips at knee level—for 10 yards

• Within one foot of contacting sled, raise your chin while maintaining low hips; pause briefly

• Explode into sled and drive it for three steps, keeping hips low

Sets/Distance: 3x10 yards, rest 60 seconds between sets
Benefits: Improved power when legs are fatigued
Coaching Points: Stay tight in your hips, and don’t let them rise. When exploding into the sled, use the same hip power that you use when making a tackle. Always keep your chest up.
Arnold: The Duck Walk fatigues your explosive speed muscles—glutes, quads, hamstrings and hips—about 80 percent before you have to drive the sled. This is how it is for Julius on the field; he performs a fatiguing action, like fighting through a blocker, then he explodes into the QB or ball carrier.
