Execution:
1
Set up on the 45° hack machine with your torso against the backrest.
2
Place one foot forward on the footplate and the other back for support.
3
Lower by bending both knees until the back knee approaches the base.
4
Press the footplate primarily with the front leg to return to the start.
Tip: the backrest takes load off your lower back — focus all tension on the front leg.
