Get Stronger
5/3/1 — First Set Last
4-day Wendler 5/3/1 with First Set Last assistance. Same main-lift wave as BBB (4 mesocycles × 4 weeks). FSL = 5×5 at the first working set's weight (vs BBB's 5×10). Lower volume — appropriate for cuts, older intermediates, or time-constrained training.

About this program
Jim Wendler's 5/3/1 with the First Set Last assistance template — a lower-volume alternative to BBB for trainees who can't recover from BBB's 50-rep assistance volume. Same main-lift wave (16 weeks across four 4-week mesocycles), same Squat / Bench / Deadlift / OHP rotation, same training-max progression. Only the assistance work differs: FSL is 5 sets × 5 reps at the FIRST working set's weight, not 5×10 at 50% TM.
Designed for intermediate trainees in any of the following: caloric deficit (BBB volume is questionable on a deficit per the Body Recomposition framework), older trainees (40+) where recovery is the limiter per the Strength framework's 40+ trainee adjustments, time-constrained windows where the 5×10 BBB assistance pushes sessions past 90 minutes, or anyone whose joints are already cooked from a hypertrophy block. Skip this if you want maximum hypertrophy carryover — switch to BBB. Equipment: barbell, rack, bench, micro- plates.
Wave structure mirrors BBB exactly: Week 1 = 65/75/85% TM × 5/5/5+, Week 2 = 70/80/90% × 3/3/3+, Week 3 = 75/85/95% × 5/3/1+, Week 4 = 40/50/60% × 5 deload. AMRAP rep count on the third main set drives TM progression (Wendler heuristic: AMRAP +5 reps over baseline = TM ready to move).
Across 16 weeks expect 7-12 kg added to squat / deadlift, 3-7 kg to bench, 1-2.5 kg to OHP. Slightly slower hypertrophy than BBB (lower weekly assistance volume) — that's the trade-off. Backed by Jim Wendler's *5/3/1 Forever* (2017) chapter on FSL.

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
First wave — establish FSL load. Conservative TM start.
- Weeks 5–862Intensity
Phase 2 · Accumulation
Mesocycle 2
Second wave at +2.5 kg upper / +5 kg lower TM.
- Weeks 9–1282Intensity
Phase 3 · Intensification
Mesocycle 3
Third wave. AMRAP rep counts will be lower as TM has climbed.
- Weeks 13–1688Intensity
Phase 4 · Testing
Mesocycle 4 — Peak / Re-test
Final wave. Re-test 1RMs in week 16 deload week.
