How GainsLog picks a substitute

  1. 1

    Same joint action

    A substitute has to work your quads through the same primary joint action as Sissy Squat: knee extension. An exercise with a different joint action trains the muscle differently, so the app treats it as variety, not a swap.

  2. 2

    Same compound or isolation type

    Sissy Squat is an isolation move, so other isolation moves rank above compound lifts.

  3. 3

    Spread across equipment

    Equipment doesn't change the ranking. The list only caps how many picks come from each type of equipment, so there is an option whether you train with barbells, dumbbells, cables, machines or your bodyweight.

FAQ

What is the best alternative to Sissy Squat?
Alternating Single Leg Extension (Machine) ranks first. It works your quads through the same joint action, knee extension, and is an isolation move.
What can I do instead of Sissy Squat at home?
Try Goblet Squat, Assisted Pistol Squat, or Pistol Squat. They need only your bodyweight or a few free weights and use the same joint action.
Will swapping Sissy Squat for an alternative slow my progress?
Not if the swap uses the same joint action and you keep pushing your sets close to failure. Log the new exercise separately and build its progression from your first session.
