This page computes historical Sinclair using the verified 2021–2024 constants: men A=0.722762521, b=193.609kg; women A=0.787004341, b=153.757kg. The documented lower limits are 32kg for men and 28kg for women; at or above b the multiplier is 1. This is not a current official IWF points result. The IWF announced GAMX and Robi as its recognized points systems on 2026-04-22. Reference-chart bars project the dated senior totals at each class limit; the open class uses b, not a guessed athlete bodyweight. The class lookup uses senior/junior IWF categories effective 2026-08-01: men 60, 65, 70, 75, 85, 95, 110, +110kg; women 49, 53, 57, 61, 69, 77, 86, +86kg. Youth categories and the six-category LA28 Olympic subsets differ; this lookup does not select them. Reference totals are the IWF’s senior records/standards snapshot published 2026-08-05, not live records. WR means retained record, WS retained standard, and NEW a new 2026 standard.

The Two Competition Lifts: Snatch and Clean & Jerk

The Snatch is a single continuous movement from the floor to fully locked-out arms overhead, with the lifter catching the bar in a deep squat. It is the more technically demanding of the two lifts, requiring exceptional speed under the bar, hip flexibility, overhead stability, and precise timing. Elite athletes complete the movement in under one second from the moment the bar leaves the platform. The Snatch requires less absolute strength than the Clean & Jerk but is far less forgiving of technical errors.

The Clean & Jerk is performed in two phases. The Clean brings the bar from the floor to the front rack position — resting on the shoulders with elbows high — by driving explosively and dropping under the bar in a squat. After standing, the athlete executes the Jerk: a sharp leg dip and drive propels the bar upward while the athlete drops into a split or squat stance to catch it overhead with locked arms. The Clean & Jerk typically produces lifts 20–30% heavier than the Snatch due to the mechanical advantage of the two-phase movement and the ability to use the leg drive of the jerk to overcome the sticking point.
