Depth Jumps
1. Stand on box with toes close to edge, feet shoulder width apart.
2. Step off (do not jump off) box and land on both feet. Immediately jump up as high as possible and reach up with both hands towards. The jump should be vertical with no horizontal movement.
4. Ground contact time should be short unlike in the diagram. Landing should be soft.Note: Start with a box height of 30cm (12in). Intensity can be increased by gradually increasing the box height to a maximum of 107cm (42in) but this is only for experienced athletes with a substantial strength training background.
