Best Arm Exercises for Strength and Size

At a Glance

Ten arm-training approaches, each built around a different goal — strength, size, endurance, volume, bodyweight-only, dumbbell, barbell, isolation, high-intensity, and advanced. Pick the one that matches what you’re actually training for right now, and treat it as a complete session rather than mixing pieces from every category at once.

Your arms respond differently depending on what you’re actually asking of them — heavy and low-rep builds strength, higher rep ranges build size and endurance, isolation work builds detail. Below are ten focused approaches, each one a workout in its own right.

The Strength-Focused Workout

ExerciseSets x RepsNotes
Heavy Barbell Curl4 x 5Twice/week. Heavy weight, biceps strength focus
Close-Grip Bench Press4 x 6Twice/week. Hits triceps, chest, shoulders
Weighted Dips3 x 51-2x/week. Advanced — triceps and shoulders
Reverse-Grip Barbell Row4 x 5Twice/week. Biceps, forearms, upper back
Heavy Hammer Curl3 x 6Twice/week. Brachialis and forearm strength

Low reps, heavy weight — this session is about building raw strength, not chasing a pump.

The Hypertrophy (Size) Workout

ExerciseSets x RepsNotes
Seated Alternating Dumbbell Curl4 x 10-122-3x/week. Bicep peak and symmetry
Overhead Triceps Extension4 x 122-3x/week. Deep stretch, long head focus
Concentration Curl3 x 122-3x/week. Strong mind-muscle connection
Skull Crushers3 x 102-3x/week. Long head of triceps

Not for beginners — these push into eccentric overload, extreme rep counts, and unconventional training tools.

How to Actually Use This

Pick one workout that matches your current goal and run it as a complete session — don’t try to mix exercises from every category into one day. Rotate to a different focus every few weeks to keep progress coming and avoid staleness. And remember: your arms are already getting real work on push and pull days, so dedicated arm sessions should supplement that, not double it into overtraining territory.

Bottom Line

Ten different ways to train arms, each built around a specific goal. Match the workout to what you’re actually chasing — strength, size, endurance, or just variety — and let your recovery, not ambition, set how often you run it.
