Stand on the foot plates in the machine and have the outside of your thighs touching the padding. With a straight back grab onto the handles for stability
Start by slowly spreading your legs apart as far as comfortable until you feel a mild stretch in your inner thighs. Then in a controlled manner retract back to just before the starting point to maintain tension. Focus on pushing from your knees. Repeat for the desired amount of repetitions then gently rest the weights.
Avoid the use of momentum or clanking the weights when finishing a repetition.
