Ways to make it easier:
- Focusing only on the Concentric or Eccentric phase
- Decreasing the Range of Motion - partial reps, only go as far as you can handle
- Decreasing the lever - bending forward or turning it into a hinge-like movement when you can no longer go down
- Using external force for support - your hands, resistance bands, a partner or something
- Regressing to an easier variation/exercise
Ways to make it harder:
- Playing with the Tempo & adding an Isometric phase (pause/hold)
- Increasing the Range of Motion - going down as far as possible
- Doing it as strict as possible
- Progressing to a harder variation/exercise
