(0:00) Sit down and place your feet roughly shoulder width apart and parallel against the middle of the platform. Then adjust the depth of the seat until your knees are bent at approximately 45 degrees.
(0:14) Push through your heels, extending your legs to a point before your legs are fully extended, then slowly retract your legs to just before the starting point to avoid clashing the weights.
(0:26) Conduct each repetition at a controlled speed both when extending and retracting your legs and please do not lock your legs out completely.
(0:38) Ensure that your knees stay aligned with your shoulders and feet, where they bend up and down in a stable and smooth motion.
(0:47) When you've completed your final repetition gently lower yourself down until the weights are caught.
(0:55) If you are using your hands to push off of your legs then select a lighter weight. Avoid having your knees bend inwards past your big toes and please again don't lock your legs out.
