Checklist for progressive overload: (1) make sure you can do the exercise perfectly with assistance (e.g., box squat); (2) make sure you can do the movement without assistance (e.g., air squat); (3) assess whether you can do the movement well with added load in eccentric position (e.g., goblet squat); (4) can you hold an eccentric position with a load while maintaining control (e.g., goblet squat, hold the bottom); (5) now you can add speed; and (6) go to fatigue
- The progression checklist might take you one session or two years – it doesn’t have to be a fixed timeline depending on experience
