How it works

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

Train four lifting workouts a week in order. Divide each lift’s weekly sets equally between its workouts, putting an extra set in the first workout when the total is odd; put the final week’s sole squat workout on the first squat day. Do the deadlift double on the first pulling day and its separate rep-out on the second, leaving one rep in reserve. Between the second and third lifting workouts, take a pool or easy-cardio recovery day of a duration you choose. Deload in week seven. Before week eleven, choose the bench-single count and weights and the back-off sets, reps and weights. Choose assistance percentage references, equipment, variations and short rest periods before lifting. Consider a predicted deadlift maximum only when planning a later cycle. Do not repeat immediately: recover in Week thirteen and train lighter for four to six weeks afterward.
