The intent of this workout is to take a break from the big barbell mover exercises. When I feel like I’m plateauing in increasing load, I find it helps to focus on ancillary exercises or variations and come back to the fundamental lifts in the next workout cycle. I also happen to doing this program in a cut, and will get back to the big basics (deadlift, low back squat, bench) in the next cycle when I’m back in maintenance.

Common questions

Yes, Strong AF 3 - 4-Day Split is completely free to follow on Boostcamp. Download the app on iOS or Android, find the program, and start your first workout immediately. All 8 weeks are fully unlocked.

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 40 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.

Strong AF 3 - 4-Day Split is structured around 4 training days per week, with rest days built in to allow for recovery. The Boostcamp app lets you reschedule sessions if your week doesn't go to plan.

The program runs for 8 weeks. The structure is designed so that each week builds on the last, with weights, volume, or intensity progressively increasing as you go.
