Main Lifts: 4x5, 1x5+
For bench press, overhead press, and barbell row, perform 4 sets of 5 reps at the same weight, then a 5th set of 5+ reps (AMRAP). The weight stays the same across all 5 sets.
Deadlift: 1x5+
Deadlift is performed for only 1 set of 5+ reps (AMRAP). Deadlifts are extremely taxing, and you're already doing rows, Romanian deadlifts, and squats throughout the week. One heavy AMRAP set is sufficient.
Squat: 2x5, 1x5+
Squat is performed for 2 sets of 5 reps followed by a 3rd set of 5+ reps (AMRAP). Since you squat twice per cycle, the total volume accumulates quickly.
AMRAP Sets (5+)
The "+" means as many reps as possible while maintaining good form. Do not grind reps to absolute failure. Stop when bar speed slows significantly or form starts to break down, leaving roughly 1-2 reps in reserve.
