About this program
Jim Wendler's 5/3/1 — four-day rotation through Squat / Bench / Deadlift / OHP, with the Boring But Big assistance template (5×10 of the same lift at 50% training-max for hypertrophy carryover). The program runs four 4-week mesocycles totaling 16 weeks: each mesocycle waves working percentages 65 → 75 → 85 → 50% (week 4 = deload), then training-max increases by 2.5 kg upper / 5 kg lower for the next cycle.
Designed for late-beginner to intermediate trainees (1-2 years of consistent training). Skip this if you're still progressing session-to-session on Novice LP or weekly on Madcow — graduate here only after weekly LP stalls. Equipment: barbell, rack, bench (commercial or home gym; microplates strongly recommended for OHP).
Per the Progressive Overload framework, training-max = 90% of true 1RM bakes in daily-variation buffer. AMRAP on the third main set is the most universally useful technique per the Set Techniques framework — the AMRAP rep count guides whether to add or hold TM next cycle (Wendler's heuristic: AMRAP +5 reps over baseline = TM ready to move). The 5×10 BBB assistance is where the hypertrophy carryover comes from per the Hypertrophy framework — direct movement-pattern volume at 50-60% TM stacks chest / quad / back growth without compromising main-lift recovery.
Caveat: BBB volume is high. Per the Body Recomposition framework, BBB on a fat-loss cut is questionable — too much volume on a deficit. Switch to 5/3/1 FSL (5×5 at first set's weight) during cuts; re-author of FSL is straightforward via this same template structure.
Across 16 weeks (four mesocycles) expect 10-15 kg added to squat / deadlift, 5-10 kg to bench, 2.5-5 kg to OHP. Backed by Wendler's *5/3/1: The Simplest and Most Effective Training System for Raw Strength* (3rd ed., 2017).

How it progresses
16 weeks across 4 phases — your coach watches the effort in your logged sets and moves the weight up the moment a load starts getting easier, so you keep climbing instead of waiting on the calendar.
- Weeks 1–462Intensity
Phase 1 · Accumulation
Mesocycle 1 — Foundation
First wave through Squat / Bench / Deadlift / OHP. Conservative start TM. Final week deloads at 40-60% to dissipate fatigue and establish the wave pattern.
- Weeks 5–862Intensity
Phase 2 · Accumulation
Mesocycle 2 — Build
Second wave at higher TM. Same week structure, +2.5 kg upper / +5 kg lower from cycle 1 starting weights.
- Weeks 9–1282Intensity
Phase 3 · Intensification
Mesocycle 3 — Push
Third wave at higher TM. Weeks 9-11 push toward intensification RPE; week 12 deloads.
- Weeks 13–1688Intensity
Phase 4 · Testing
Mesocycle 4 — Peak / Re-test
Final wave. Week 15 (5/3/1+) AMRAP sets are the program's strength signal. Re-test 1RMs in week 16 deload week to set the next cycle's TMs.
