Body Part: Triceps

Description

The Machine Triceps Extension is an isolation exercise targeting the triceps brachii muscle. It involves extending the elbows against resistance provided by a machine, allowing for controlled and focused engagement of the triceps. This exercise is ideal for building strength and mass in the triceps while minimizing involvement of other muscle groups.

How to Perform

Adjust the seat height so that your upper arms are parallel to the floor when gripping the handles.
Sit down and firmly plant your feet on the floor, ensuring your back is supported by the seat.
Grip the handles with a neutral or overhand grip, depending on machine design.
Start with your elbows bent at approximately 90 degrees.
Extend your arms by pushing the handles forward until your elbows are fully extended but not locked.
Pause briefly at the top of the movement to maximize contraction.
Slowly return to the starting position by bending your elbows in a controlled manner.
Repeat for the desired number of repetitions.

What Muscles Work

Primary Muscle:

Tips

Ensure that your elbows remain stationary throughout the movement to isolate the triceps effectively.
Avoid using momentum; focus on a slow and controlled movement to maximize muscle engagement.
Keep your core engaged and maintain a neutral spine to prevent unnecessary strain on your lower back.
Adjust the weight appropriately; start with a lighter weight to perfect your form before increasing resistance.
Breathe out as you extend your arms and inhale as you return to the starting position.

Common Mistakes

Failing to adjust the seat height, leading to improper alignment of elbows and shoulders.
Allowing the elbows to flare out, reducing triceps engagement.
Using momentum to lift the weight instead of controlled movements.
Not fully extending the arms, limiting the range of motion.
Locking the elbows at the bottom of the movement, increasing joint stress.
Letting the wrists bend excessively, causing strain and reducing effectiveness.
Leaning forward or backward, disrupting posture and muscle engagement.
Selecting too much weight, compromising form and control.
