Max Effort Day is a feature in Fitbod that helps you test and improve your estimated strength for a given exercise. On a Max Effort Day, you’ll see two AMRAP (as many reps as possible) sets added after your working sets. These workouts help the app recalibrate your performance and deliver more personalized recommendations.
Max Effort Days are automatically scheduled based on your exercise history and help you:
- Push beyond your previous limits
- Refine future weight, rep, and set suggestions
