This program is the culmination of years of my personal experience in working out, as well as insights gathered from fitness influencers and knowledgeable individuals in the fitness community. It’s not just a workout plan but a reflection of what has worked for me personally. Some exercises in this program are my favorites because they have delivered great results or simply felt good to perform. The foundation of this program is a basic double progression method. In simple terms, you’ll work within a set and rep range, and once you hit the top of that range for all sets, you’ll increase the weight. For instance, if you have 3 sets of 5-8 reps (3x5-8), you’ll gradually add reps each week until you reach 3x8 with the current weight. After that, you’ll increase the weight and start over at the lower end of the range. For optimal recovery, rest between sets should be 90 to 150 seconds, with 2 minutes being ideal if you’re unsure. Methods explained: Super set - doing two exercises in a succession without rest (preferably these 2 exercises should work different muscle / be complementary groups so you can train one while resting the other one) Squat Method Use Periodization (5-Week Blocks) Structure: Week 1: Start light (e.g., 140 kg for top set of 3). Weeks 2-5: Add 5-10 kg weekly (e.g., 145, 150, 155, 160 kg). Peak: Week 5 is your strongest. If performance drops in weeks 6-7, your peak is week 5. Next Block: Start slightly heavier than the previous block (e.g., 145 kg in block 2). Repeat 5-week cycles, aiming to end heavier each block. Dominik Sky’s weighted pull-up + dip program is a straightforward strength-building method starting with bodyweight or a 5 kg plate. You begin with 3 sets of 3 reps (3x3) at the chosen weight, aiming to reach 5 sets of 5 reps (5x5). Each session, you increase the reps or sets (e.g., 3x3, then 3x4, 3x5, up to 5x5). Once you hit 5x5 with good form, you add 5 kg (or 10 kg for advanced lifters) and restart at 3x3. Train with 3-5 minutes rest between sets, focusing on strict form and full range of motion to build pulling strength.

Common questions

Yes, Steins;Mass is completely free to follow on Boostcamp. Download the app on iOS or Android, find the program, and start your first workout immediately. All 18 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 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.

Steins;Mass 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 18 weeks. The structure is designed so that each week builds on the last, with weights, volume, or intensity progressively increasing as you go.

Steins;Mass 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.
