What is the best exercise for bigger arms?

The close-grip bench press for triceps and the barbell curl for biceps. These are the foundational compound and isolation movements that allow the heaviest loading for each muscle. However, for maximum arm size, you need overhead tricep work (to target the long head in its stretched position) and incline curls (to target the bicep long head in its stretched position). The best arms are built by combining heavy compound work with targeted isolation that emphasizes the stretched position of each muscle.

How many sets for arms per week?

Ten to fourteen direct sets per week for triceps and eight to twelve for biceps. This does not count the indirect work from pressing (which trains triceps) and rows or pulldowns (which train biceps). If you are doing heavy bench press and overhead press, your triceps are already getting six to ten indirect sets. Add six to eight direct tricep isolation sets on top. For biceps, heavy rows and pulldowns provide four to eight indirect sets — add six to eight direct curl sets. Start at the lower end and increase if arms are a weak point.

Should I train arms on their own day?

Either approach works. Dedicated arm days allow more volume and focus. Training arms after pushing (triceps) or pulling (biceps) is more time-efficient. For most people on a PPL split, adding two to three sets of bicep curls at the end of pull day and two to three sets of tricep work at the end of push day is enough. If arms are a priority, add a dedicated arm session once per week on top of the indirect work from your compound days.

Why are my arms not growing despite curling every day?

Three likely reasons. First, you are neglecting triceps — they are two-thirds of arm size. Second, you are curling too heavy with momentum instead of controlled, strict form. Third, you may be overtraining by curling daily without recovery. Arms are small muscles that need forty-eight to seventy-two hours to recover. Train them intensely two to three times per week with proper rest between sessions. Focus on progressive overload — adding one to two reps or a small amount of weight each week — rather than daily high-volume curling.

Do I need to train forearms directly?

Most lifters do not need direct forearm work if they are doing heavy deadlifts, rows, and curls without straps — these exercises train grip and forearms indirectly. If your forearms are visibly lagging or your grip fails before your back does on deadlifts, add four to six sets of wrist curls and reverse curls per week. Farmer carries are another excellent option that builds both grip strength and forearm size simultaneously. Use straps on back exercises if grip is limiting your back development, and train forearms separately.

Best Arm Exercises Ranked (2026)

Arm size is determined primarily by the triceps (two-thirds of upper arm mass) and biceps (one-third). Most lifters make the same mistake: they overtrain biceps — doing endless curl variations — while neglecting the triceps that actually make up the majority of arm size. This ranking fixes that imbalance.

The first seven exercises target triceps because they contribute more to overall arm mass. Exercises eight through twelve target biceps. The final two exercises are forearm movements for complete arm development. Each exercise links to its full guide. Browse all arm movements in our triceps, biceps, and forearms exercise libraries.

How We Ranked These Exercises

We evaluated arm exercises on four criteria:

Muscle activation: Studies measuring triceps, biceps, and forearm recruitment across movements.
Overload potential: Can you add significant weight over time? Compound movements like close-grip bench press rank higher than single-joint isolation exercises.
Practicality: Available in most gyms, reasonable injury risk, works for multiple experience levels.
Muscle contribution to arm size: Triceps exercises rank higher because the triceps make up two-thirds of upper arm mass. Building bigger triceps has more impact on arm size than building bigger biceps.

The 14 Best Arm Exercises

Triceps (Exercises 1-7)

Close-Grip Bench Press

The best compound tricep exercise. Close-grip bench press allows the heaviest loading of any tricep movement — strong pressers move 300+ lbs. It trains all three tricep heads (long, lateral, and medial) along with the chest and front delts. The narrow grip shifts emphasis from chest to triceps while still allowing progressive overload through heavy compound pressing.

Primary muscles: Triceps (all three heads). Secondary: Chest, front delts. Best for: Overall tricep strength and mass, foundation building.

Full close-grip bench press guide

Overhead Cable Extension

The best isolation exercise for the tricep long head — the largest of the three heads and the one responsible for the most upper arm mass. The overhead position places the long head under maximum stretch, driving stretch-mediated muscle growth. Cables provide constant tension throughout the movement. If you only do one tricep isolation exercise, make it this one.

Primary muscles: Triceps (long head emphasis). Secondary: None significant. Best for: Long head development, tricep mass, the “horseshoe” look.

Full overhead cable extension guide

Weighted Dips

A compound movement with massive loading potential. Weighted dips train the triceps through a full range of motion while also hitting the chest and shoulders. Lean upright and keep elbows close to emphasize triceps over chest. Progressive overload via weight belt makes dips one of the best exercises for building tricep strength and size simultaneously.

Primary muscles: Triceps, chest. Secondary: Front delts. Best for: Overall pushing strength, compound tricep development.

Full weighted dips guide

Tricep Pushdown (Cable)

The staple tricep isolation exercise found in every gym. Pushdowns target the lateral and medial heads of the triceps — the heads visible when your arm is at your side. Easy to set up, easy to load, and easy to feel. The cable provides constant tension. Pair pushdowns with overhead work for complete tricep coverage.

Primary muscles: Triceps (lateral and medial heads). Secondary: None significant. Best for: Lateral/medial head development, high-rep pump work.

Full tricep pushdown guide

Skull Crusher (Lying Tricep Extension)

A classic barbell or EZ bar isolation exercise for the long head. Lying on a bench with arms extended, you lower the weight toward your forehead (hence the name) and press back up. Skull crushers allow moderate-heavy loading and a deep stretch on the triceps. Watch for elbow stress at higher weights — use controlled form.

Primary muscles: Triceps (long head emphasis). Secondary: None significant. Best for: Long head isolation, moderate-heavy loading.

Full skull crusher guide

V-Bar Pushdown

A pushdown variation using the V-bar attachment for a neutral grip. The angled handles are slightly more comfortable on wrists than straight bars and allow a stronger squeeze at the bottom. Good lateral head emphasis with the ability to use heavier loads than rope pushdowns. A solid variation to rotate into your program.

Primary muscles: Triceps (lateral and medial heads). Secondary: None significant. Best for: Heavier pushdown loading, wrist comfort.

Full V-bar pushdown guide

Diamond Push-Up

The bodyweight tricep exercise. Diamond push-ups place your hands close together in a diamond shape, shifting emphasis from chest to triceps. Studies show surprisingly high tricep activation — comparable to many weighted exercises. No equipment needed. Excellent for high-rep burnout sets, home training, or when traveling without gym access.

Primary muscles: Triceps. Secondary: Chest, front delts. Best for: Home training, travel, high-rep finishers.

Full diamond push-up guide

Biceps (Exercises 8-12)

Barbell Curl

The foundational bicep exercise. The barbell curl allows the heaviest loading of any curl variation, making it ideal for progressive overload. It trains both heads of the biceps (long and short) through the full range of motion. Simple, effective, and a staple in every serious arm program. Use strict form — no swinging.

Primary muscles: Biceps (both heads). Secondary: Brachialis, forearms. Best for: Overall bicep strength and mass, foundation building.

Full barbell curl guide

Incline Dumbbell Curl

The best curl variation for the bicep long head and peak. The inclined bench position places the bicep in a deep stretch at the bottom of the movement — exactly where stretch-mediated muscle growth occurs. This makes incline curls one of the most effective exercises for building the bicep peak. Use a 45-60 degree incline.

Primary muscles: Biceps (long head emphasis). Secondary: Brachialis. Best for: Bicep peak, long head development, stretch-position training.

Full incline dumbbell curl guide

Preacher Curl

The cheat-proof curl. The preacher bench braces your upper arms against the pad, eliminating momentum and forcing strict bicep isolation. You cannot swing or use body English — the biceps do all the work. Excellent for mind-muscle connection and for lifters who tend to cheat on standing curls. Use barbell, EZ bar, or dumbbells.

Primary muscles: Biceps (short head emphasis). Secondary: Brachialis. Best for: Strict isolation, mind-muscle connection, short head focus.

Full preacher curl guide

Hammer Curl

The neutral-grip curl for arm thickness. Hammer curls target the brachialis — the muscle that sits under the biceps and pushes the peak up when developed — and the brachioradialis (the meaty forearm muscle). Building the brachialis makes arms look thicker from all angles. Essential for complete arm development.

Primary muscles: Brachialis, brachioradialis. Secondary: Biceps. Best for: Arm thickness, brachialis development, forearm tie-in.

Full hammer curl guide

Cable Curl

Constant tension curling. Cables maintain resistance throughout the entire range of motion, including at the top of the curl where dumbbells and barbells lose tension. This makes cable curls excellent for peak contraction and pump-focused sets. Good finishing exercise after heavier barbell or dumbbell work.

Primary muscles: Biceps. Secondary: Brachialis. Best for: Peak contraction, pump sets, constant tension training.

Full cable curl guide

Forearms (Exercises 13-14)

Wrist Curl (Barbell)

Direct forearm flexor training. Wrist curls build the underside of the forearm — the muscles responsible for grip strength and forearm aesthetics. High reps work best (15-25) because the forearm flexors are endurance-oriented. Sit on a bench with forearms resting on your thighs, palms up, and curl the barbell using only your wrists.

Primary muscles: Forearm flexors. Secondary: None significant. Best for: Forearm size, grip strength, underside forearm development.

Full wrist curl guide

Reverse Curl

The forearm extensor and brachioradialis builder. Reverse curls use an overhand grip, shifting emphasis from biceps to the top of the forearm. Building this area creates the thick forearm look visible when arms are at your sides. Can be done with barbell, EZ bar, or dumbbells. Moderate weight with controlled form works best.

Primary muscles: Brachioradialis, forearm extensors. Secondary: Biceps. Best for: Top-of-forearm development, brachioradialis, grip strength.

Best Arm Exercises by Goal

For Overall Arm Size

Top 3: Close-grip bench press, overhead cable extension, barbell curl. The compound press builds tricep strength and mass, overhead work targets the long head (largest tricep head), and barbell curls are the foundation for bicep development.

For Bicep Peak

Top 3: Incline dumbbell curl, preacher curl, cable curl. Incline curls stretch the long head (responsible for the peak), preacher curls isolate the biceps with strict form, and cable curls maximize peak contraction at the top.

For Tricep Horseshoe

Top 3: Overhead cable extension (long head), tricep pushdown (lateral head), close-grip bench press (all three heads). The horseshoe shape requires development of all three heads, with special emphasis on the long head through overhead work.

For Home / No Gym

Top 3: Diamond push-ups, dumbbell curls, resistance band pushdowns. With a single pair of dumbbells, a resistance band, and your bodyweight, you can build impressive arms at home.

How to Build an Arm Workout From This List

You do not need all 14 exercises. Here is how to structure a complete arm session:

Pick 2 tricep exercises: 1 overhead (long head) + 1 pushdown (lateral head) (3-4 sets each, 8-12 reps)
Pick 2 bicep exercises: 1 heavy curl (barbell) + 1 stretch-position curl (incline) (3-4 sets each, 8-12 reps)
Optional forearm work: Wrist curls or reverse curls (2-3 sets, 15-20 reps)

Total: 4-5 exercises, 12-16 sets per arm workout. Train arms 2x per week for fastest growth. Note that arms get significant indirect work from pressing (triceps) and pulling (biceps) — adjust direct arm volume based on your compound work. For detailed volume guidelines, see our sets per muscle group per week guide.

The Most Common Arm Training Mistake

Prioritizing biceps over triceps

Walk into any gym and you will see lifters doing endless curl variations while skipping tricep work entirely. This is backwards. The triceps make up two-thirds of upper arm mass — if your arms are small, the solution is more tricep work, not more curls.

Think about it: would you rather grow the muscle that is one-third of your arm or the muscle that is two-thirds? For maximum arm size, tricep volume should equal or exceed bicep volume.

The fix: Aim for a 2:1 ratio of tricep-to-bicep work. If you do 8 sets of bicep work per week, do 10-12 sets of tricep work. Prioritize compound movements like close-grip bench and dips, then add isolation work.
