The purpose of this program is to help lose excess body fat, build lean muscle, and increase overall strength by incorporating a mix of strength training and high-intensity conditioning. Compound movements target multiple muscle groups at once which helps to maximize calorie burn and improve metabolism. This program is designed to sculpt your body, improve your fitness level and boost your confidence. This program will incorporate progressive overload in order to build strength. There is a level of monotony from week to week in order to focus on lifting more weight with similar movements. This will be achieved by increasing the RPE on movements every other week. This program is intended to keep you consistent and motivated without overwhelming you.

Common questions

Yes, The Lean Machine Workout is completely free to follow on Boostcamp. Download the app on iOS or Android, find the program, and start your first workout immediately. All 6 weeks are fully unlocked.

This program is built around a dumbbell only. 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.

The Lean Machine Workout is structured around 5 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 6 weeks. The structure is designed so that each week builds on the last, with weights, volume, or intensity progressively increasing as you go.

The Lean Machine Workout 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.
