Scientific Basis

Epley Formula (1985):
1RM = Weight × (1 + Reps/30)

Most accurate for 1-10 rep range. Validated in peer-reviewed research.

Brzycki Formula (1993):
1RM = Weight / (1.0278 - 0.0278 × Reps)

Alternative formula, slightly more conservative estimates.

Training Percentages:

Based on established strength training protocols. RPE (Rate of Perceived Exertion) scale: 5-10 (5=easy, 10=maximal effort).
