How it works

The program’s own rules, as Catalyst runs them.

Repeat A1, B1, A2 and B2 in order, resting after B1 and B2. Choose positive starting weights and the increments you will use. Main lifts progress through three sets of five, four of four, five of three and six of two, with as many reps as possible (AMRAP) on the last set. Keep your weight after successful four-by-four work; add your chosen increment after success at the other stages. After a miss at the final stage, restart at eighty-five percent, rounded down to that increment. Assistance and pulling work use three sets of ten, then eight, then six; a final-stage miss restarts at seventy-five percent, rounded down. Increase accessory weight at the upper rep total and reduce it below the lower total. Completing zero repetitions leaves your weights and stages unchanged.

What you need
