Swapping Leg Extension mid-workout?
In the app, tap Swap on any exercise: GainsLog suggests alternatives ranked the same way (same joint action, then same type) and keeps a separate progression for each one.
How GainsLog picks a substitute
1
Same joint action
A substitute has to work your quads through the same primary joint action as Leg Extension: knee extension. An exercise with a different joint action trains the muscle differently, so the app treats it as variety, not a swap.
2
Same compound or isolation type
Leg Extension is an isolation move, so other isolation moves rank above compound lifts.
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 Leg Extension?
- Sissy Squat (Bodyweight and home) ranks first. It works your quads through the same joint action, knee extension, and is an isolation move.
- What can I do instead of Leg Extension at home?
- Try Sissy Squat, Assisted Pistol Squat, or Goblet Squat. They need only your bodyweight or a few free weights and use the same joint action.
- Will swapping Leg Extension 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.
