Why train at specific percentages?

Training at specific percentages of your 1RM is the foundation of scientific strength programming. Different percentages target different adaptations - heavy percentages (85–95%) build maximal strength, moderate percentages (70–85%) build size and strength simultaneously, and lighter percentages (50–70%) develop technique and endurance.

What is Wendler 5/3/1?

5/3/1 by Jim Wendler is one of the most popular strength programs in the world. It rotates weekly intensity across three weeks (5s, 3s, 1s) with an AMRAP set on the last set to accumulate volume and push past your calculated percentages. The fourth week is a deload.

How often should you retest your 1RM?

Retesting every 4–8 weeks is common for intermediate lifters. Beginners can progress more frequently (every 2–4 weeks). Using submaximal AMRAPs (as in 5/3/1) lets you estimate your 1RM without maxing out every training cycle.
