AMRAP 18 mins: 15 Box Jumps (24/20 in), 12 Push Presses (115/75 lb), 9 Toes-to-Bar.
Primary movement: Box/PP/T2B
Open 12.3 is the archetypal long Open triplet: 18 minutes of box jumps, push presses at a meaningful 115/75, and toes-to-bar. Nothing gates you, everything drains you - the jumps tax the legs and lungs, the push press turns into a grind exactly when the legs stop helping, and the T2B quietly bill the grip. Ten-plus rounds means 150+ box jumps: this workout is where rebounding athletes learned about achilles respect.

Where does your Open 12.3 Rx land?
Log it once and the app places you on this table automatically, then tracks the trend.
Step down from the box from round one - 18 minutes of rebounding is an injury lottery with a bad prize pool. Push press unbroken while the dip-drive stays crisp (usually 8-10 rounds), then 7-5. T2B in 5-4 to protect the grip you'll want in round 9. Aim for level 90-100 second rounds; this scoreboard is built by the boring middle ten minutes.
Scaled: 20 in box or step-ups, 75/55 lb push press, hanging knee raises.
