If you're hitting the gym with dreams of sleeve-busting arms, you're in the right place. Building impressive biceps and triceps isn’t just about curling random dumbbells—it’s about strategy, intensity, and knowing which moves actually deliver results. Whether you're chasing that peak on your biceps or looking to add serious thickness to your triceps, this workout plan is your ticket to arm gains that turn heads.
The Science Behind Arm Growth
Your arms aren’t just for show—they’re functional powerhouses. The biceps (front of the arm) handle pulling motions, while the triceps (back of the arm) do most of the pushing. To maximize growth, you need to hit both with a mix of heavy lifts and high-rep burnout sets. The key? Progressive overload (gradually increasing weight or reps) and proper form to avoid turning your workout into an elbow-wrecking disaster.
The Ultimate Biceps Blast
1. Barbell Curls – The Classic Mass Builder
Start with the OG of biceps exercises. Stand with feet shoulder-width apart, grip the barbell underhand, and curl it up while keeping your elbows locked at your sides. No swinging—cheating here just cheats your gains. Aim for 4 sets of 8-12 reps with a weight that makes the last few reps feel like a battle.
2. Dumbbell Hammer Curls – For That Brachialis Pop
These target the brachialis (the muscle under your biceps), giving your arms that thick, 3D look. Hold dumbbells with a neutral grip (palms facing each other) and curl them up slowly. Control the descent—don’t let gravity do the work. Shoot for 3 sets of 10-12 reps.
3. Incline Dumbbell Curls – Stretch for Growth
Sitting on an incline bench forces a deeper stretch at the bottom of the movement, which research shows can lead to more muscle growth. Let your arms hang fully extended, then curl up with a slight pause at the top. 3 sets of 10-12 reps should leave your biceps screaming.
Triceps: The Secret to Bigger Arms
Fun fact: Your triceps make up about two-thirds of your arm’s size. If you’re skipping triceps work, you’re leaving gains on the table.
1. Close-Grip Bench Press – Heavy Duty Triceps Builder
This isn’t just a chest exercise—using a narrow grip shifts focus to your triceps. Keep elbows tucked and lower the bar to your lower chest, then press up explosively. Go for 4 sets of 6-8 reps with a challenging weight.
2. Skull Crushers – The Ultimate Triceps Burn
Lie on a bench, hold an EZ bar or dumbbells, and lower them toward your forehead (without actually crushing your skull, please). Keep elbows steady—flaring them turns this into a shoulder exercise. Aim for 3 sets of 10-12 reps.
3. Triceps Dips – Bodyweight Beast Mode
If you can do weighted dips, even better. Lean forward slightly to emphasize triceps over chest, and go deep for maximum stretch. Shoot for 3 sets to failure or add weight for extra intensity.
