Strength and Size, no heavy Overhead Press. To determine your weight jumps each week for the main lift, add 1% of your 1 rep max for every extra rep you did on last week's AMRAP. For example, If you are working through sets of 6 and performed 10 on the AMRAP, that is 4 extra reps so your weight jump would be 4% of your 1 rep max. If I’m operating off of a 1 rep max of 400lbs, that’s 16lbs (we can safely round down to 15) added to last week's working weight. You'll need to calculate this manually, but it's not hard. This is called autoregulation.

This program is built around a garage gym. Make sure you have consistent access before starting, since the progression model assumes you can perform the same movements week over week.

Each session typically takes around 70 minutes to complete. That estimate covers your working sets but doesn't account for warm-up or rest between sets, so budget a little extra time when you're first learning the movements.

The program runs for 12 weeks. The structure is designed so that each week builds on the last, with weights, volume, or intensity progressively increasing as you go.
