Nutrition Guidlines: Starting Week 1 Calories: Protein: 1 g per pound of Bodyweight Carbs: 1.5 - 2 g per pound of bodyweight (1.5g on Non weight training days / 2g on weight training days) Fats: 0.5 g per pound of bodyweight. Supplementation: Vitamin D3 Multivitamin Creatine Fish Oil If you are unable to get through the workout and feel lack of strength or energy don't drop Calories. When workouts become easier add more weights in smaller Increments. Keep tracking your progress and your food. Sleep for 9 hrs. Daily. Thw biggest supplement you need is that of a consistency. Because the program is super high volume. Hence, I would recommend you to start of with light weights and try to complete all exercises and all sets. And slowly and periodically increase the load. If your nutrition and Sleep remains on point, I can bet that the results will follow. Always remember, To achieve something extraordinary you need to put in extraordinary efforts. If you want the results that others aren't, You got to do things that others can't.

Common questions

Yes, 12 Weeks Muscle Building Program 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 180 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.

12 Weeks Muscle Building Program is structured around 7 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.

12 Weeks Muscle Building Program 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.
