Instructions

1

Sit on the machine with back firmly against the backrest, feet flat on the floor or footrest. Position upper arms parallel to the ground with elbows at approximately 90 degrees, gripping the handles with an underhand grip (palms facing up).

2

Ensure shoulders are relaxed and depressed away from ears. Maintain a neutral spine throughout. Grip the handles firmly with both hands positioned shoulder-width apart or slightly narrower.

3

Slowly lower the handles by extending the elbows in a controlled manner, allowing the weight to pull the arms toward full extension. Stop just before the elbows lock out completely to maintain tension on the biceps.

4

Drive the handles upward by flexing the elbows and contracting the biceps, bringing the handles toward your shoulders. Squeeze the biceps at the top of the movement, then return to the starting position with control.

Overview

When programming for Biceps Brachii growth, the Lever Triceps Extension stands out as a highly efficient Strength choice. Performing this movement with Leverage machine forces your stabilizer muscles to work in tandem with the primary movers, translating to functional strength and enhanced muscular endurance.

Benefits

Significantly enhances the structural integrity and power of the Biceps Brachii.
Improves overall Upper Arms stability and proprioception during heavy loads.
Promotes balanced muscular development by effectively recruiting the Biceps Brachii and associated synergists.
Reduces the likelihood of Upper Arms injuries by reinforcing connective tissue strength.
Acts as a highly scalable Strength movement, perfect for both beginners and elite athletes.

Common Mistakes

Failing to achieve a full range of motion, which drastically limits Biceps Brachii engagement.
Shrugging the shoulders or compensating with secondary muscles rather than isolating the Biceps Brachii.
Using excessive momentum to swing the Leverage machine rather than controlling the eccentric phase.

Pro Tips

Think about pulling from your elbows rather than your hands to better isolate the Biceps Brachii and minimize bicep/forearm takeover.

Muscle Anatomy

The primary driver is the Biceps Brachii. However, the movement also recruits Brachialis, Brachioradialis, Forearm Flexors to maintain control of the Leverage machine.

Beginner Tips

If you are new to the Lever Triceps Extension, focus on mastering the movement pattern with zero weight before adding Leverage machine.
