Arm Day Workout

A full arm day that trains biceps and triceps from every angle using barbells, dumbbells, and cables, the complete session for adding real size to your arms.

Program Overview

This arm day workout trains both the biceps and triceps thoroughly, alternating between them so each gets a brief rest while the other works. It uses barbells for heavy loading, dumbbells for independent arm work, and cables for constant tension, which is the combination that hits the arms from every angle. Remember that your triceps make up around two thirds of your upper arm, so this session gives them equal billing rather than treating them as an afterthought. Every exercise comes with a form video.

Who this workout is for

Intermediate lifters who want a dedicated arm session with full gym equipment. Pairs with push, pull, and leg day workouts.

  • You want noticeably bigger arms

Phase 1: Build the Base (Weeks 1-4)

Run the session twice a week with at least two days between. Alternate a biceps and a triceps movement throughout. These are smaller muscles, so prioritize a strong squeeze and strict form over heavy weight.

Loading in Phase 1

Use weights you control for all reps with one or two in reserve. Add load whenever a movement feels comfortable across all sets.

Nutrition Guidance

Building muscle needs enough fuel and protein behind your training. Our macro calculator sets your calories and protein targets, and our recipes make hitting them easier. If you are choosing between programs, our guide on choosing the right plan for your goals is worth a read.

The Basics

  • Calories: Eat in a slight surplus of 250 to 500 calories per day to build muscle while minimizing fat gain. Our macro calculator sets your starting point.
  • Protein: 1.6 to 2.2g per kg of bodyweight daily to drive recovery and muscle growth. Browse our recipes for ideas.
  • Hydration: Drink water consistently, especially on training days.
  • Sleep: Seven to nine hours per night. Muscle is built during recovery, not during the session.

Use the macro calculator to set your calories and protein for your goal, then track your bodyweight as a weekly average and adjust in small increments based on the trend.

Program FAQ

Is a dedicated arm day worth it?
If arms are a priority for you, yes. Arms do get worked during pressing and pulling, but a dedicated session lets you train them with focus and volume while they are fresh, rather than squeezing in a few tired sets at the end of another workout.
Why does this workout include so much triceps work?
Because the triceps make up around two thirds of your upper arm. If you want bigger arms and only train biceps, you are leaving most of your potential size on the table. Equal attention to both is what actually increases arm size.
How often should I train arms?
Twice a week works well. Arms are small muscles that recover quickly and also get indirect work from your other sessions, so they respond well to being trained a couple of times a week with focused, quality volume.
Should I go heavy on arm exercises?
Moderate weight with strict form beats heavy weight with swinging. Arms respond well to controlled reps, a full range of motion, and a strong contraction. Use enough weight to challenge you within the rep range, but never at the cost of your technique.
How long should I run this workout?
Run it for eight weeks chasing progression, then take a lighter week before repeating it heavier. Arms reward consistency and a strong mind-muscle connection over time.
