Dual Frequency Build is not your average bro-split. While it retains the satisfying structure of isolating muscle groups across the week, it elevates the concept by ensuring strategic frequency — hitting each muscle group around twice per week, either directly or indirectly, to maximize hypertrophic response and neurological adaptation. Each workout is built around one or two primary muscle groups, followed by secondary work that complements the main lift. For example: - Chest day includes triceps activation. - Back day includes hamstrings via deadlifts. - Leg day includes light rowing for posterior chain reinforcement. - Shoulder day includes light chest work to fill frequency gaps. - Arm day wraps up the week with focused isolation, light legs and core engagement. Repetition ranges: 4–8 reps on primary lifts for strength and motor unit recruitment. 8–12 reps for most hypertrophy movements. 12–15+ reps for isolations, mind-muscle connection, and volume-based fatigue. Design considerations: - Deadlifts on back day allow the program to hit hamstrings twice (with RDLs on leg day) while keeping squat focus on quads - Chest-supported rows reduce spinal fatigue on back day after deadlifts - Shoulder work is balanced between overhead pressing and lateral/rear delt volume, reducing risk of imbalances - Arm day serves as both a finisher and a recovery pump session — high reward, low systemic cost. I have added some quad-focused exercises here to give the quads some more frequency. -No extreme overlapping ensures you never crush the same muscle two days in a row, yet frequency remains high enough for adaptation You are entirely free to switch up the exercises if you feel like it. Suggested Weekly layout: Monday: Chest + Light Triceps Tuesday: Back + Hamstrings (Deadlift) Wednesday: Shoulders + Light Chest Thursday: Legs + Light Back Friday: Rest/Active recovery Saturday: Arms + Core + Quads Weekend: Rest or Active Recovery

Common questions

Yes, Dual Frequency (brosplit inspired) is completely free to follow on Boostcamp. Download the app on iOS or Android, find the program, and start your first workout immediately. All 8 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.

Dual Frequency (brosplit inspired) 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 8 weeks. The structure is designed so that each week builds on the last, with weights, volume, or intensity progressively increasing as you go.

Dual Frequency (brosplit inspired) 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.
