The COMPLETE arm growth guide

Summary

Tom Cartmell presents an arm-focused training approach built around training arms while fresh, using relatively low volume, and tracking gradual strength progress. The video also promotes his Peak Arms Protocol community, which he says provides a training and diet system, along with direct coaching.

Key Training Strategies

• Pair opposing muscle groups: Rather than training chest with triceps and back with biceps, Cartmell recommends chest with biceps and back with triceps. He says this reduces arm pre-fatigue and lets you train arms while they’re fresher.
• Keep other muscle-group work modest: He suggests reducing chest and back training to a maintenance level—around four sets per muscle group in a workout—to leave more energy for arms.
• Use low volume and focus on hard sets: His approach generally involves two sets per exercise, taken close to or to failure, rather than adding many sets or training primarily for a pump.
• Order exercises from hardest to easiest: Start with demanding movements, such as heavier exercises, and finish with simpler isolation movements. This is intended to help you continue progressing on exercises later in the session.
• Use moderate rep ranges and adequate rest: He recommends roughly 6–10 reps, with 3–5 minutes of rest between sets. He suggests timing rest periods rather than starting the next set early.
• Track workouts and progress gradually:
  • Record weights and reps in an app or notes.
  • Aim to improve slightly over time—often by about one rep, or by a smaller increment for more advanced trainees.
  • Better technique with the same number of reps can also count as progress.
• Address plateaus deliberately: If progress stalls for two or three sessions, he suggests changing the exercise or temporarily increasing the rep range—for example, to 10–20 reps—before returning to the lower range when ready.
• Avoid constantly changing programs: Stick with a routine long enough to learn and progress on its exercises. Don’t switch just because a new exercise is popular online.
• Don’t use pump or soreness as the main measure of success: Cartmell argues that strength progression matters more than how pumped or sore your arms feel.
• Avoid “more is always better” training: He discourages excessive volume, frequent all-out workouts, and treating gym training like a race. He frames training as a long-term process that should remain sustainable and enjoyable.

Promotion in the Video

Cartmell invites viewers to join his Peak Arms Protocol community. He says it includes an arm-focused program, diet guidance, access to him for questions, and— for viewers joining through the video—an action-planning call.
