How to use this 5/3/1 calculator
This calculator gives you a complete cycle for Jim Wendler’s popular 5/3/1 strength program. You enter an estimated one-rep max, and the tool calculates your training max plus all working sets for each week. It also gives you a recommended training max for your next cycle.
If you are brand new to 5/3/1, the key idea is simple: train submaximally, progress steadily, and prioritize long-term consistency over short-term hero lifts.
What is 5/3/1?
5/3/1 is a strength framework built around four main lifts: squat, bench press, deadlift, and overhead press. Each cycle usually runs four weeks:
- Week 1: 3 sets at 65%, 75%, 85% for 5+ reps on the last set
- Week 2: 3 sets at 70%, 80%, 90% for 3+ reps on the last set
- Week 3: 3 sets at 75%, 85%, 95% for 1+ reps on the last set
- Week 4: Deload, lighter work (commonly 40%, 50%, 60%)
The percentages are based on your training max, not your true all-out max. That’s why lifters can make progress for months and years without burning out.
Why training max matters
Use 90% and stay honest
Most people do best when training max is set to 90% of estimated 1RM. It keeps bar speed high, technique clean, and recovery manageable.
Progress in small jumps
Traditional cycle jumps are:
- Upper body lifts: +5 lbs (or +2.5 kg)
- Lower body lifts: +10 lbs (or +5 kg)
These small jumps add up quickly while minimizing plateaus.
How to run your sets
The final set is the driver
In standard 5/3/1, the final work set each week is an “AMRAP” set (as many reps as possible), with one rule: stop before form breaks. Think “quality effort,” not grinder reps.
Assistance work options
This calculator also includes a BBB (Boring But Big) suggestion. If enabled, you’ll see one simple target weight for 5 sets of 10 reps, typically around 50% of training max.
Common mistakes to avoid
- Starting with a training max that is too high
- Failing AMRAP sets due to poor sleep or rushed rest times
- Changing templates every two weeks instead of committing
- Ignoring conditioning and mobility work
- Testing true maxes too often
FAQ
Can beginners use this?
Yes, but beginners should prioritize form and recovery. If you are very new to lifting, a simpler linear progression may build your base faster for a few months first.
Should I use pounds or kilograms?
Use whichever unit your gym setup supports. Set a practical rounding increment so loading the bar is quick and repeatable.
How often should I recalculate?
Recalculate each cycle after applying the small training max increase. Do not chase daily maxes. Slow progress is still progress.
Final note
The best 5/3/1 plan is the one you can execute for the next 6 to 12 months. Keep your training max conservative, hit quality reps, recover hard, and let consistency do the heavy lifting.
