Muscle Builder: Arm Focus *Intermediate This hypertrophy-focused workout plan emphasizes Arm development by strategically increasing weekly set volume while keeping intensity at a moderate level. By progressively adding sets each week, you'll continuously challenge your muscles, promoting ongoing growth and progress. The plan ensures balanced muscle targeting, aiming to enhance both muscle size and strength over time. If you're new to any exercise, select a weight suitable for the prescribed reps and perceived exertion. Start each session with a 5-10 minute warm-up on an elliptical or treadmill. Rest periods between sets range from 1 to 2 minutes, adjusting based on exercise type. It is also recommended to do warm up sets before your working sets, especially with compound movements. Create a custom warm-up template with 3 sets. 30% for 10 reps 50% for 5 reps 100% for 2 reps On rest days, engage in light activity like mild weight training or cardio to facilitate active recovery. Feel free to swap exercises within the same muscle group, maintaining similar complexity (compound or isolation movements). Adjust rep ranges and intensity (perceived exertion) as needed, typically aiming for 8-12 reps for compound exercises and 10-16 reps for isolations. The program includes a Deload week to decrease intensity and volume, allowing for full recovery and injury prevention, supporting long-term strength and muscle gains.

Common questions

Yes, Muscle Builder: Arm Focus is completely free to follow on Boostcamp. Download the app on iOS or Android, find the program, and start your first workout immediately. All 5 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 60 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.

Muscle Builder: Arm Focus 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 5 weeks. The structure is designed so that each week builds on the last, with weights, volume, or intensity progressively increasing as you go.

Muscle Builder: Arm Focus 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.
