Powerlifting Log: Plate Math and 1RM, Handled
Powerlifting logging is mostly about three lifts, heavy singles and doubles, and knowing your estimated 1RM without a max-effort attempt every week. IRONSLOG’s plate calculator, RPE column and per-lift 1RM chart are built around exactly that, with the 38-exercise powerlifting category available in the library alongside barbell squat, bench and deadlift variations.
What does IRONSLOG handle specifically for the big three lifts?
A per-side plate calculator works out the exact plates for any target weight on the squat, bench or deadlift, and an optional RPE column records how hard a top set felt on a 1-10 scale if that’s part of your autoregulation. Every completed set is checked against your logged history to auto-flag a PR.
How accurate is the estimated 1RM for a powerlifter’s programming?
It’s calculated with the Epley formula from your top set on a given day — useful for tracking a trend over weeks and months, not a substitute for a tested max on meet day. The chart toggles between top-set weight and estimated 1RM so you can read either number depending on what your programming actually calls for.
Does the exercise library have real powerlifting movements, not just generic barbell lifts?
Yes — 38 exercises are categorized specifically as powerlifting, alongside barbell-equipment variations of the squat, bench press and deadlift filed under strength, so accessory and competition-specific movements are both searchable.
