What This Means
Training Max is 90% of your true 1RM. This is used in programs like 5/3/1 to ensure consistent progression and prevent missed reps. Your working sets are calculated as percentages of this training max, not your true 1RM.
Scientific Basis
Training Max Formula:
Training Max = 1RM × 0.90
Developed by Jim Wendler for the 5/3/1 program. Using 90% of your true max allows for consistent weekly progression and accounts for daily fluctuations in strength. This ensures you can complete all prescribed reps even on "off" days.
