💪 Arm Workouts

Arm Anatomy and Training Principles

Your arms consist of two primary muscle groups: biceps (front) and triceps (back). Despite being smaller muscles, arms respond well to direct training and add significant visual impact to your physique.

Biceps Anatomy

• Biceps Brachii: The main muscle with two heads (long head and short head)
• Long Head: Outer bicep, responsible for the peak
• Short Head: Inner bicep, adds width when viewed from front
• Brachialis: Underneath biceps, pushes biceps up when developed
• Brachioradialis: Forearm muscle that assists in curling

Triceps Anatomy

• Triceps Brachii: Three-headed muscle on back of arm
• Long Head: Inner tricep, largest head
• Lateral Head: Outer tricep, creates horseshoe shape
• Medial Head: Deep muscle underneath, always active
• Note: Triceps make up 2/3 of arm mass—prioritize them for bigger arms

Best Bicep Exercises

Mass Building Movements

1. Barbell Curl

• The king of bicep exercises for overall mass
• Allows heaviest loading
• Targets both bicep heads
• Execution: Stand with barbell, curl to shoulders, control descent
• Sets/Reps: 3-4 sets × 8-12 reps

2. Dumbbell Curl

• Greater range of motion than barbell
• Allows supination (twist) at top for peak contraction
• Can do alternating or simultaneously
• Sets/Reps: 3-4 sets × 10-12 reps per arm

3. Hammer Curl

• Targets brachialis (underneath biceps)
• Also hits brachioradialis (forearm)
• Neutral grip reduces elbow stress
• Adds arm thickness when viewed from side
• Sets/Reps: 3 sets × 10-12 reps

Peak Development Movements

4. Incline Dumbbell Curl

• Emphasizes long head (bicep peak)
• Full stretch at bottom position
• Use 45-60 degree incline
• Sets/Reps: 3 sets × 10-12 reps

5. Preacher Curl

• Isolates biceps, eliminates momentum
• Emphasizes short head (inner bicep)
• Great for peak contraction
• Sets/Reps: 3 sets × 10-15 reps

6. Cable Curl

• Constant tension throughout range
• Multiple grip options (bar, rope, handles)
• Excellent for pump and metabolic stress
• Sets/Reps: 3 sets × 12-15 reps

Best Tricep Exercises

Mass Building Movements

1. Close-Grip Bench Press

• Best compound movement for tricep mass
• Allows heaviest loading
• Targets all three heads
• Hands shoulder-width apart (not too narrow)
• Sets/Reps: 3-4 sets × 6-10 reps

2. Weighted Dips

• Excellent compound for triceps and chest
• Lean forward for chest, upright for triceps
• Add weight when bodyweight becomes easy
• Sets/Reps: 3-4 sets × 8-12 reps

3. Overhead Tricep Extension (Dumbbell or Cable)

• Best exercise for long head development
• Arms overhead stretches long head maximally
• Use moderate weight, focus on stretch and contraction
• Sets/Reps: 3-4 sets × 10-12 reps

Isolation Movements

4. Tricep Pushdown (Cable)

• Excellent lateral head isolation
• Multiple attachment options (rope, bar, V-bar)
• Keep elbows pinned at sides
• Sets/Reps: 3 sets × 12-15 reps

5. Skull Crushers (Lying Tricep Extension)

• Great for overall tricep mass
• Can use barbell, EZ-bar, or dumbbells
• Lower to forehead or behind head
• Sets/Reps: 3 sets × 10-12 reps

6. Diamond Push-Ups

• Bodyweight option for triceps
• Hands form diamond shape
• Great for home training or finishers
• Sets/Reps: 3 sets × 10-20 reps

Complete Arm Workout Programs

Arm Training Techniques

1. Drop Sets

Perform set to failure, immediately reduce weight 20-30%, continue to failure.

• Example: Bicep curl 40 lbs × 10 → 30 lbs × 8 → 25 lbs × 6
• Use on last set of exercise
• Creates metabolic stress, extreme pump

2. Supersets

Pair biceps and triceps exercises back-to-back with no rest.

• Example: Barbell curl → Tricep pushdown (repeat 3-4 rounds)
• Time-efficient, increases intensity
• Arms can handle high volume due to quick recovery

3. 21s

Classic bicep technique for brutal pump.

• 7 reps bottom half (bottom to 90 degrees)
• 7 reps top half (90 degrees to top)
• 7 reps full range
• That's 1 set = 21 total reps
• Use moderate weight (40-50% of max)

4. Peak Contraction Holds

Hold contracted position for 2-3 seconds at top of each rep.

• Maximizes time under tension
• Creates stronger mind-muscle connection
• Particularly effective for bicep peak development

Common Arm Training Mistakes

1. Using Too Much Weight/Momentum

• Swinging, using back/shoulders to curl weight
• Solution: Use weight you can control with strict form

2. Not Training Triceps Enough

• Triceps are 2/3 of arm mass but often undertrained
• Solution: Do more tricep volume than bicep volume

3. Neglecting Grip Variations

• Always using same curl/extension variation
• Solution: Rotate grips (supinated, neutral, pronated)

4. Training Arms Too Often

• Training arms 5-6x per week with inadequate recovery
• Solution: 2-3x per week is optimal for most people

5. Forgetting Compound Movements

• Only doing isolation curls and extensions
• Solution: Include close-grip bench and weighted dips
