Disclaimer – this is an overreaching programme it is designed to push your 1 rep max over 12 weeks and will be a stressful period of training. Don’t run this programme back to back and make sure to perform a lighter 4-6 weeks of training after to allow your body to acclimatise. Disclaimer 2- I did not create this program. I found it online and because I couldn’t find it here , I made it available so I could do this again. Assistance Work Assistance work will work off a 3-week linear cycle, you should look to keep the weight well within your maximum capabilities, try to take shorter rest periods and have general fatigue wear you down and get you near failure. Generally, I would advise you work the following muscle groups 2-4x per week. Lats (pulldown or pull up using a mixture of grips) Rhomboids, Traps and Lats (rowing using a mixture of machines, dumbbells and grips) Shoulders (presses or raises) Lower back (hypers and rev hypers) Abs (bracing using plank, weighted plank, rollouts or gymnastics progressions)

Common questions

Yes, Cast Iron Strength is completely free to follow on Boostcamp. Download the app on iOS or Android, find the program, and start your first workout immediately. All 12 weeks are fully unlocked.

This program is built around a full 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 90 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.

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

Cast Iron Strength is available inside the Boostcamp app, free on iOS and Android. Once you download the app, you can search for the program by name. The app tracks all your sets and weights automatically, so you always know exactly what to do next session.
