Program
5/3/1 Boring But Big
Boring But Big keeps the 5/3/1 main work intact and bolts a 5×10 supplemental block onto every session. The strength stays; the size comes from the second half of the workout.

How it works
The main sets follow Wendler's 5/3/1 percentage scheme. Training max is 90% of true max. Week 1: 65/75/85% for sets of 5. Week 2: 70/80/90% for sets of 3. Week 3: 75/85/95% for sets of 5/3/1+. Week 4 is deload. Training max goes up 5 lb for upper lifts and 10 lb for lower lifts after each cycle.
The Boring But Big supplemental work is where the hypertrophy stimulus lives. After the main 5/3/1 sets, you do 5 sets of 10 reps at 50-60% of training max on the same lift. The weight feels light early and brutal by set 4. The 50 total reps at moderate load drive muscle growth without interfering with the main strength work.
The template runs indefinitely. Wendler recommends starting supplemental sets at 50% and adding 5% every cycle until you hit 70%, then backing off. Four days per week: Monday squat, Tuesday bench, Thursday deadlift, Friday press — or any similar split with at least one day of rest between lower-body days.

Fine print
Caveats
- BBB is a hypertrophy template, not a peaking program. Expect slower progress on the 5/3/1 main lifts than with lower-volume templates like Triumvirate or First Set Last. Accept that trade — you are trading some top-end strength progression for muscle growth.
- Do not start supplemental work above 50%. The volume is the stimulus. Ramping too fast means grinding through the last two sets, which is not the point. Five clean sets of 10 at 50% produces more growth than three grindy sets of 10 at 65%.
- If 5×10 on both squat and deadlift in the same week wrecks your recovery, swap to the BBB variant where supplemental work uses the opposite lift — squat supplemental after deadlift main, and vice versa. Wendler explicitly includes this option for lifters who struggle with the combined lower-body volume.
