Perform this exercise without your prosthetic.
Stand with your feet shoulder-width apart wearing a weighted vest.
Lower into a squat with your knees aligned over the toes and feet flat on the floor and raise your arms in front of you.
Keep your back long, your head upright, and your eyes looking forward.
Jump upwards out of the squat at the same time swinging your arms behind you and extending through your hips, knees, and ankles.
Land back into the squat position with the knees bent to absorb the impact through the leg and hips.
Pause in this position for a second and then repeat the jump from the start position.
