  2. 02

    Sit with your back pressed firmly against the backrest, grasping the handles.

  3. 03

    Extend your legs upwards, squeezing your quadriceps at the peak contraction.

    Hold briefly at the top, feeling the burn in your quads.

  5. 05

    Slowly lower the weight back to the starting position, controlling the eccentric phase.
