What Muscles Do Larsen Press Work? Complete Anatomy Guide

The Larsen press is a bench press variation performed with your legs extended straight and feet hovering off the floor—eliminating leg drive entirely. Named after Norwegian powerlifter Adrian Larsen, this variation builds pure upper body pressing strength.

Quick Answer

Primary muscles: Pectoralis major (maximum), anterior deltoids (very high), triceps (very high)

Secondary muscles: Core (high—stabilization), serratus anterior (moderate), lats (moderate)

The Larsen press isolates the upper body pressing muscles by removing any assistance from the legs.

Why Remove Leg Drive?

Identifies Upper Body Weakness

If your Larsen press is much weaker than your regular bench, your chest and triceps need work—you're relying on leg drive.

Builds Raw Pressing Strength

No compensation from legs means the chest, shoulders, and triceps must do ALL the work.

Reduces Arch

With legs extended, your arch naturally flattens. This changes range of motion and emphasizes different chest fibers.

Competition Carryover

Building raw pressing strength transfers to competition bench when you add leg drive back.

The Larsen Press Movement

Setup

| Body Part | Position | |-----------|----------| | Legs | Extended straight, feet off floor | | Back | Slight arch (less than normal bench) | | Shoulders | Retracted, on bench | | Grip | Standard bench grip |

The Descent

| Muscle | Action | Activation | |--------|--------|------------| | Pecs | Eccentric control | High | | Anterior delts | Lowering bar | High | | Lats | Pulling bar to chest | Moderate | | Core | Preventing rotation | High |

Lower the bar with control—no leg tension to stabilize you.

The Press

| Muscle | Action | Activation | |--------|--------|------------| | Pecs | Pressing bar up | Maximum | | Anterior delts | Pressing assist | Very High | | Triceps | Elbow extension | Very High | | Core | Maintaining position | High |

Press without any leg drive—pure upper body power.

Primary Muscles Worked

Pectoralis Major

| Region | Emphasis | |--------|----------| | Sternal (middle/lower) | Very High | | Clavicular (upper) | High |

Your chest works maximally because there's no leg drive to assist. Every pound pressed comes from your pressing muscles.

Anterior Deltoids

Your front delts work throughout the press. With no leg compensation, they contribute more than in a standard bench.

Triceps

Your triceps extend the elbows to lockout. The Larsen press builds tricep strength that transfers to all pressing.

Secondary Muscles

Core (Stabilization)

Without feet on the floor, your core must work to prevent:

• Lateral movement
• Rotation
• Body shifting

This is significant stabilization work.

Serratus Anterior

Assists with scapular stability throughout the press.

Latissimus Dorsi

Your lats help control the bar path and provide some stability.

Larsen Press vs Standard Bench

| Aspect | Larsen Press | Standard Bench | |--------|-------------|----------------| | Leg drive | None | Yes | | Arch | Reduced | Full | | Stability | Lower | Higher | | Weight used | Less (10-15%) | More | | Upper body emphasis | Maximum | High | | Core demand | Higher | Lower |

The Larsen press is harder pound-for-pound due to no assistance.

Programming Larsen Press

As Primary Movement

• 3-5 sets of 5-8 reps
• Work up to heavy sets
• Expect 10-15% less than bench max
• Full rest between sets

As Accessory

• After competition bench
• 3-4 sets of 8-12 reps
• Moderate weight
• Focus on pressing strength

For Technique Work

• Light to moderate weight
• Focus on bar path
• Feel the chest/tricep work
• Build mind-muscle connection

For Weak Point Training

• If weak off chest or at lockout
• Builds raw pressing capacity
• 3-4 week training blocks

Technique Cues

Setup

1. Lie on bench with shoulders retracted
2. Extend legs straight
3. Lift feet slightly off floor (hover)
4. Grip bar at normal width
5. Core braced

The Press

1. Lower bar with control
2. Touch chest at normal spot
3. Press through chest and triceps
4. No body English—pure press
5. Maintain stable position throughout

Common Mistakes

| Mistake | Why It's Bad | Fix | |---------|-------------|-----| | Feet touching floor | Not a Larsen press | Hover feet throughout | | Excessive movement | Unstable, cheating | Brace core, stay tight | | Same weight as bench | Will fail | Reduce weight 10-15% | | Legs bent | Wrong position | Legs straight and extended | | Bouncing off chest | Cheating | Touch and press |

Leg Position Options

Classic Larsen (Legs Extended, Feet Hovering)

• Standard version
• Maximum instability
• Feet 1-2 inches off floor

Feet Up on Bench

• Feet resting on bench
• More stable than classic
• Still no leg drive

Legs Extended, Heels on Floor

• Slight modification
• More stable
• Still eliminates meaningful leg drive

Adrian Larsen's original style: Legs straight, feet hovering, not touching anything.

Weight Expectation

Most lifters can Larsen press 85-90% of their bench press. Factors:

• Upper body strength relative to leg drive reliance
• Core stability
• Practice with the variation

If your Larsen press is much lower, you're relying heavily on leg drive.

Who Should Do Larsen Press

Excellent For:

• Powerlifters building raw pressing strength
• Those who rely too much on leg drive
• Upper body strength development
• Bench press accessory work
• Core and stability training

Considerations:

• Not for maximum weight attempts
• Requires good body control
• May feel awkward initially
• Less weight = less ego

Benefits Beyond Chest

Identifies Weaknesses

Reveals reliance on leg drive versus true pressing strength.

Core Development

Unusual core challenge builds stability.

Technique Awareness

Builds awareness of pressing mechanics without compensation.

Competition Carryover

Raw pressing strength developed transfers when leg drive returns.

Sample Programming

Accessory Block (4 Weeks)

• Week 1: 4x8 @ 65% bench max
• Week 2: 4x6 @ 70%
• Week 3: 4x5 @ 75%
• Week 4: 4x4 @ 80%

In Weekly Program

• Day 1: Competition Bench (main)
• Day 2: Larsen Press (accessory, 3x8)

Technique Day

• Larsen Press: 5x5 @ moderate weight
• Focus on perfect reps

Key Takeaways

✅ Larsen press works chest, front delts, and triceps with no leg drive
✅ Legs extended, feet hovering off floor
✅ Expect 10-15% less weight than regular bench
✅ Reveals reliance on leg drive
✅ Builds pure pressing strength
✅ Core works harder for stabilization
✅ Great accessory for powerlifters
✅ Named after Adrian Larsen (Norwegian powerlifter)

---

The Larsen press strips away the leg drive and asks: how strong is your press really? Extend those legs, hover your feet, and find out. Build the raw pressing strength that makes everything else easier.
