Hack Squats


  • Lay back-rest with the pads on your shoulders and your feet shoulder width apart on the platform.
  • Push off the platform using your heels and keeping you back flat against the support, then unlock the weight. Do not lock your knees out.
  • Slowly lower the weight by bending at the knees until your knees are 90 degrees.
  • By pushing with the heels of your feet, slowly return to the standing position, contracting your thighs.


  • Keep your back flat against the back rest. Going too low may cause injury to your knees.
