Growing bigger arms requires understanding both the bicep and tricep anatomy and applying the training principles that develop both muscle groups: compound bilateral work for foundational mass on both biceps and triceps, varied bicep angles (incline for long head, hammer for brachialis), varied tricep angles (overhead for long head, pushdowns for lateral head), dedicated isolation work alongside compound, and adequate frequency and volume across both muscle groups. The triceps comprise about two-thirds of upper arm mass, so growing bigger arms requires equal or greater tricep emphasis than bicep work. Most lifters who want bigger arms but struggle to grow them are making one or more of these mistakes: training only biceps (neglecting the larger tricep group), using only one bicep angle (missing long head and brachialis), avoiding overhead tricep work (missing long head), training arms too infrequently, or running insufficient volume across both muscle groups. The fix involves: 1) compound work for both groups (barbell curls for biceps, close grip bench and dips for triceps), 2) varied bicep angles (incline curls for long head, hammer curls for brachialis), 3) varied tricep angles (overhead extensions for long head, pushdowns for lateral head, lying extensions for variety), and 4) adequate frequency (1 to 2 times per week) and volume (12 to 18 sets per muscle group per week).
Below are ten of the most effective exercises for growing bigger arms, covering compound bicep work (barbell curl), varied bicep angles (dumbbell incline curl, dumbbell hammer curl, cable incline biceps curl, cable unilateral bicep curl), compound tricep work (barbell close grip bench press, triceps dip), and varied tricep angles (cable triceps pushdown, barbell seated overhead triceps extension, dumbbell lying triceps extension). Together they form a complete arm-growth program. A 45 to 60-minute arm-focused session pulled from this list, performed 1 to 2 times per week, produces strong arm development for any lifter focused on building bigger arms.
Barbell Curl
The Barbell Curl performs barbell biceps curls. The pattern is foundational compound bicep mass work.
For arm growth, the barbell curl is foundational bicep mass work. The pattern allows heaviest bilateral bicep loading. Run it for 4 sets of 6 to 10 reps as primary bicep mass work.
Stand with feet hip-width holding a barbell at the front of the thighs with underhand grip. Keep the elbows tucked at the sides. Curl the barbell up by bending the elbows. The biceps work hard through elbow flexion. Squeeze the biceps hard at peak contraction. Lower under control. Avoid using momentum from the legs or trunk – keep the curl strict for maximum bicep loading. The pattern is foundational for bicep mass building – lifters with the largest biceps typically have built them on consistent heavy barbell curl training.
Dumbbell Incline Curl
The Dumbbell Incline Curl performs dumbbell curls on an incline bench. The stretched position emphasizes the long head of the bicep.
For arm growth, the incline curl produces direct long head bicep loading. The stretched position emphasizes the long head. Run it for 3 to 4 sets of 8 to 12 reps as long head bicep work.
Set up an incline bench at about 45 to 60 degrees. Sit on the bench with the back against the pad. Hold dumbbells at the sides with arms hanging straight down (palms facing forward). Curl the dumbbells up by bending the elbows. The biceps stretch deeply at the bottom and contract hard at the top. Squeeze hard at peak contraction. Lower under control. The incline position emphasizes the long head of the bicep that creates the bicep peak appearance and is essential for complete bicep development.
Dumbbell Hammer Curl
The Dumbbell Hammer Curl performs dumbbell curls with a neutral grip. The pattern hits the brachialis and brachioradialis.
For arm growth, the hammer curl develops the brachialis and brachioradialis – critical for complete arm thickness. Run it for 3 sets of 8 to 12 reps as primary brachialis work.
Stand with feet hip-width holding dumbbells at the sides with neutral grip (palms facing the body). Curl the dumbbells up while maintaining the neutral grip throughout. The brachialis (the muscle under the bicep) and brachioradialis (forearm) work hard through elbow flexion. Squeeze hard at peak. Lower under control. The pattern is critical for complete arm development – the brachialis pushes the bicep outward and contributes substantially to overall arm thickness.
Barbell Close Grip Bench Press
The Barbell Close Grip Bench Press performs bench press with a close grip. The pattern produces compound tricep mass work.
For arm growth, the close grip bench press is the foundational compound tricep mass-builder. The pattern allows heavy bilateral tricep loading. Run it for 4 sets of 6 to 10 reps as primary tricep mass work.
Lie on a flat bench with the eyes directly under the barbell. Grip the bar with hands shoulder-width apart (or slightly closer). Unrack the bar and position it over the chest. Lower the bar to the lower chest by bending the elbows while keeping them relatively close to the sides (not flared). Press the bar back up by extending the arms. The triceps work hard through compound pressing. The pattern is foundational for tricep mass – the close grip emphasizes triceps over chest in the press.
Triceps Dip
The Triceps Dip performs bodyweight dips on parallel bars. The pattern produces strong compound tricep work.
For arm growth, dips are foundational compound tricep work. Stay upright (not leaned forward) for tricep emphasis. Run it for 3 to 4 sets of 6 to 15 reps as compound tricep work.
Position yourself between parallel bars with the body suspended above. Stay upright (do not lean forward – upright position emphasizes triceps). Lower the body by bending the elbows until the upper arms are roughly parallel to the floor. Press back up by extending the arms. The triceps work hard through compound pressing. The pattern produces strong tricep mass work. Progress with weighted dips (dip belt) for advanced strength as bodyweight reps become easy.
Cable Triceps Pushdown on Floor
The Cable Triceps Pushdown performs tricep pushdowns with a cable. The pattern produces direct tricep isolation through pure elbow extension.
For arm growth, the tricep pushdown is foundational tricep isolation work. Run it for 4 sets of 10 to 15 reps as primary tricep isolation work.
Set a cable to the highest setting with a straight or rope attachment. Stand facing the cable. Hold the attachment with hands at chest height with elbows tucked at the sides. Push the attachment down by extending the elbows while keeping the upper arms stationary against the sides. The triceps work hard through pure elbow extension. Squeeze the triceps hard at peak extension. Return under control. The pattern produces direct tricep isolation that complements compound pressing for complete tricep development.
Cable Incline Biceps Curl
The Cable Incline Biceps Curl performs incline curls with a cable. The continuous tension produces unique long head loading.
For arm growth, the cable incline curl produces continuous tension on the long head of the bicep. Run it for 3 sets of 10 to 12 reps as cable bicep work.
Set up an incline bench in front of a cable machine with the cable set to the lowest position. Sit on the incline bench with the back against the pad and hold the cable handle with the working arm hanging down. Curl the cable up by bending the elbow. The bicep works through continuous cable tension throughout the range (unlike dumbbells where tension varies). Squeeze hard at peak. Return under control. The pattern produces unique bicep loading complementary to dumbbell curls.
Barbell Seated Overhead Triceps Extension
The Barbell Seated Overhead Triceps Extension performs overhead tricep extensions with a barbell. The overhead position emphasizes the long head of the tricep.
For arm growth, the overhead tricep extension is critical for long head tricep development. The overhead position emphasizes the long head. Run it for 3 to 4 sets of 8 to 12 reps as long head tricep work.
Sit on a bench with the back against an upright pad. Hold a barbell overhead with both hands. Lower the barbell behind the head by bending the elbows while keeping the upper arms vertical and tucked close. The long head of the tricep stretches deeply at the bottom and contracts hard through extension. Press the barbell back overhead by extending the elbows. The pattern is critical for complete tricep development – the long head requires the overhead stretched position for maximum loading.
Cable Unilateral Bicep Curl
The Cable Unilateral Bicep Curl performs single-arm cable curls. The pattern produces continuous tension unilateral bicep work.
For arm growth, the unilateral cable curl provides continuous tension and addresses imbalances. Run it for 3 sets of 10 to 12 reps per arm as unilateral bicep work.
Set a cable to the lowest setting. Stand sideways to the cable with the working arm farthest from the cable. Hold the cable handle in the working hand with the arm at the side. Curl the handle up by bending the elbow. The working bicep works through continuous cable tension. Squeeze hard at peak. Lower under control. Switch arms between sets. The unilateral pattern allows full focus on each arm individually and addresses left/right imbalances.
Dumbbell Lying Triceps Extension
The Dumbbell Lying Triceps Extension performs lying tricep extensions with dumbbells. The pattern produces direct tricep isolation through extension.
For arm growth, the lying tricep extension produces direct tricep loading through pure elbow extension. Run it for 3 sets of 10 to 12 reps as direct tricep isolation work.
Lie on a flat bench holding dumbbells over the chest with arms straight and palms facing each other. Lower the dumbbells back toward the head by bending the elbows while keeping the upper arms relatively vertical. The triceps work hard through pure elbow extension. Press the dumbbells back up by extending the elbows. Squeeze the triceps hard at peak. The pattern produces direct tricep loading and is excellent for breaking through tricep plateaus when other patterns stall.
How To Program These Workouts
A productive arm-growth session pulls 6 to 8 exercises from the list above, balancing biceps and triceps. A common balanced session: barbell curl (compound bicep), dumbbell incline curl (long head bicep), dumbbell hammer curl (brachialis), barbell close grip bench press (compound tricep), barbell seated overhead triceps extension (long head tricep), cable triceps pushdown (lateral head tricep). For mass focus: barbell curl, barbell close grip bench press, triceps dip, dumbbell incline curl. For isolation focus: cable incline biceps curl, cable unilateral bicep curl, cable triceps pushdown, dumbbell lying triceps extension. Run compound work for 3 to 4 sets of 6 to 10 reps, isolation work for 3 to 4 sets of 8 to 15 reps. Total session covers 18 to 24 working sets balanced between biceps and triceps.
Train arms 1 to 2 times per week for optimal growth. Most lifters who struggle to grow arms are training them only once per week with insufficient volume. Increasing to twice weekly often produces measurable arm growth within 8 to 12 weeks. The optimal pattern: one heavy day focused on compound strength (barbell curls, close grip bench, dips for 6 to 10 reps) and one volume day focused on hypertrophy (incline curls, hammer curls, tricep pushdowns, overhead extensions for 10 to 15 reps). Schedule with at least 48 hours between dedicated arm sessions. Note that arms are activated heavily in chest and back training, so total weekly arm activation includes work from those sessions.

Final Thoughts
Growing bigger arms requires applying the right training principles consistently over time: compound work for both biceps and triceps, varied angles for complete development across all arm muscle groups, dedicated isolation alongside compound work, balanced bicep and tricep emphasis, and adequate frequency and volume to drive growth. The combination of barbell curls, incline curls, hammer curls, cable curls, close grip bench press, dips, tricep pushdowns, overhead extensions, and lying extensions covers every functional pattern of the arms and produces broader development than any single exercise approach. Most lifters who consistently apply these principles see measurable arm growth within 12 to 16 weeks, often producing visible improvements in arm size and definition. For lifters who have struggled to grow arms despite training, the combination of equal bicep AND tricep emphasis (most lifters undertrain triceps), higher frequency (twice weekly), and varied angles for both muscle groups typically breaks through the plateau.
Stay focused on tricep development as much as bicep development. The most common mistake lifters make in arm training is overemphasizing biceps (because biceps are visible from the front) while undertraining triceps (which comprise two-thirds of arm mass). The fix: train triceps with at least equal volume and intensity to biceps. Include both compound tricep work (close grip bench, dips) and dedicated isolation across multiple angles (overhead extensions for long head, pushdowns for lateral head). Combined with proper bicep training across multiple angles, balanced bicep AND tricep emphasis produces the well-developed arms that pure bicep training never achieves.
Frequently Asked Questions
Why aren’t my arms growing?
Most lifters with stubborn arms make one or more of these mistakes: 1) overemphasizing biceps and undertraining triceps (triceps are 2/3 of arm mass), 2) using only one bicep angle (missing long head and brachialis), 3) avoiding overhead tricep work (missing long head), 4) training arms only once per week, 5) running insufficient volume across both muscle groups. The fix: train triceps with at least equal volume to biceps, use varied bicep angles (incline, hammer, regular), include overhead tricep extensions, train arms twice weekly, target 12+ working sets per muscle group per week.
Should I focus on biceps or triceps for bigger arms?
Focus on triceps as much or more than biceps. The triceps comprise about two-thirds of upper arm mass, so growing bigger arms requires equal or greater tricep emphasis. Most lifters undertrain triceps because they’re less visible from the front, but tricep development is the primary driver of overall arm size. Train both with equal volume and intensity, with particular attention to the long head of the tricep (overhead extensions) which provides the bulk of tricep mass.
What’s the best exercise for bigger arms?
Compound work for both bicep and tricep are most effective. Barbell curls produce the heaviest possible compound bicep loading. Close grip bench press and triceps dips produce the heaviest compound tricep loading. Combined with varied bicep angles (incline curls for long head, hammer curls for brachialis) and varied tricep angles (overhead extensions for long head, pushdowns for lateral head), these form the foundation of arm growth. The fastest gains come from combining heavy compound work for both groups with dedicated isolation across varied angles.
How often should I train arms for growth?
1 to 2 times per week, with 2 weekly sessions producing better growth for most. The optimal pattern: one heavy day focused on compound strength (barbell curls, close grip bench, dips for 6 to 10 reps) and one volume day focused on hypertrophy (incline curls, hammer curls, tricep pushdowns, overhead extensions for 10 to 15 reps). Schedule with at least 48 hours between dedicated arm sessions. Note that arms are activated in chest and back training, so total weekly arm activation includes work from those sessions.
Are dips good for triceps?
Yes – excellent compound tricep work. Dips produce strong compound tricep loading that builds tricep mass through bodyweight and weighted progression. Stay upright (not leaned forward) to emphasize triceps over chest. Most successful arm programs include dips as primary compound tricep work, typically 6 to 15 reps for 3 to 4 sets. Progress with weighted dips (dip belt) for advanced strength as bodyweight reps become easy. Combined with close grip bench and overhead extensions, dips form the foundation of compound tricep development.
