Complete Arm Workout: Build Bigger Biceps and Triceps

Coach Amirul Haziq

Big arms are one of the most desired goals for gym goers across Malaysia. While arms get indirect work from pulling and pushing exercises, direct arm training is necessary to maximise their size and shape.

Understanding Arm Anatomy

Your upper arm is roughly two-thirds triceps and one-third biceps. This means if you want bigger arms overall, triceps deserve at least as much attention as biceps — something many beginners overlook.

The biceps brachii has a long head (outer) and short head (inner). The brachialis sits underneath the biceps and pushes it up when developed, making your arm look bigger. The triceps has three heads — long, lateral, and medial — all of which need to be trained for complete development.

Best Bicep Exercises

Barbell curls allow you to use the most weight and are the staple bicep builder. Stand upright, keep your elbows pinned to your sides, and curl without swinging your body.

Incline dumbbell curls place a deep stretch on the long head of the biceps. Set the bench to 45 degrees and let your arms hang fully before curling.

Hammer curls target the brachialis and forearms. Hold the dumbbells with a neutral grip (palms facing each other) and curl without rotating your wrists.

Concentration curls isolate the biceps completely by bracing your elbow against your inner thigh. Excellent for building the peak of the bicep.

Best Tricep Exercises

Close grip bench press is the best compound movement for triceps. Use a grip just inside shoulder width and keep your elbows tucked close to your body.

Overhead dumbbell extensions stretch the long head of the triceps, which is its largest portion. Hold a single dumbbell with both hands behind your head and extend upward.

Cable pushdowns with a rope or straight bar are perfect for isolating the lateral and medial heads. Keep your elbows pinned and squeeze at the bottom.

Dips hit the triceps hard, especially when you keep your torso upright rather than leaning forward.

Sample Arm Workout

  1. Barbell curls — 3 sets of 8 to 10 reps
  2. Close grip bench press — 3 sets of 8 to 10 reps
  3. Incline dumbbell curls — 3 sets of 10 to 12 reps
  4. Overhead dumbbell extensions — 3 sets of 10 to 12 reps
  5. Hammer curls — 2 sets of 10 to 12 reps
  6. Cable pushdowns — 2 sets of 12 to 15 reps

Alternate between a bicep and tricep exercise for an efficient workout that takes about 40 minutes.

Training Tips for Bigger Arms

Use strict form. Swinging heavy dumbbells with your whole body does nothing for arm growth. Use a weight you can control through the full range of motion.

Train arms twice per week. Smaller muscles recover faster than large ones. Two dedicated arm sessions or arm work tagged onto other training days provides enough stimulus for growth.

Do not neglect forearms. Farmer's walks and wrist curls develop the lower arm, creating a more complete look and improving your grip strength for heavier compound lifts.

The Patience Factor

Arms grow slowly compared to larger muscle groups. Adding even two centimetres to your arm circumference in six months is solid progress. Stay consistent with your training and nutrition, and the results will follow.
