Weighted Pull-Up & Dip 1RM Streetlifting Calculator

Compute Total System Load 1RM, Epley/Brzycki streetlifting projections, and relative strength ratios (% Bodyweight)

Answer-First Biomechanical Summary (TL;DR)

Unlike barbell calculators that ignore the athlete's own mass, the ENIX Weighted Pull-Up & Dip 1RM Calculator computes true streetlifting Total System Load (Bodyweight + External Belt Weight) across Epley and Brzycki equations, then subtracts bodyweight to yield your exact external belt 1RM (+kg) and Relative Strength Ratio (× BW). This prevents the 25–40% estimation errors common when applying standard gym 1RM formulas to weighted calisthenics.

Total_1RM = (BW + Added_kg) × (1 + Reps / 30) | External_1RM = Total_1RM − BW

Quantitative Readiness & Strength Benchmark Tiers

In weighted calisthenics, lifting +20 kg for 5 reps at 80 kg bodyweight means moving 100 kg of Total System Load for 5 reps (Total 1RM ≈ 116.7 kg -> +36.7 kg external 1RM, or 1.46× BW). Applying the Epley formula to the +20 kg plate alone would erroneously predict only +23.3 kg.

Frequently Asked Biomechanical Questions

Why must Bodyweight be included in the Weighted Pull-Up 1RM formula?

During a Weighted Pull-Up or Dip, your prime movers lift ~93–100% of your bodyweight plus the weight on the dip belt. Calculating 1RM on Total System Load (BW + Added Weight) is the only biomechanically valid way to project rep maxes and percentage-based working sets (e.g., 80% of Total 1RM).
