Load & 1RM-Equivalent Calculator
Estimate how much load your body angle and foot placement put on the straps, and what that works out to as a 1RM-equivalent.
kg
The load comes from a share of your own bodyweight.

How this is worked out: load on the straps is estimated as bodyweight × cos(body angle from the floor) × 0.7,
so a near-horizontal position loads roughly 65–70% of your bodyweight (in line with inverted-row and push-up research). The
1RM-equivalent uses the Epley formula (load × (1 + reps ÷ 30)). These are estimates to guide progression, not exact one-rep-max testing.
