The three-headed muscle along the back of everybody's arms is a power dynamo and a pillar of posture. Your triceps straightens your elbows to create propulsive force and pulls your arms back when you stand.

A thread on how to build a balanced muscle for power and posture.
Your Triceps has three heads:

1. Long
2. Lateral
3. Medial

A deficiency in either of these muscle fibres hinders the tone of your arms. This imbalance pulls the puts excess pressure on your elbows or shoulders. The tension also pulls your ams in a slouched position.
The position of your shoulders sets which head dominates the extension work, according to a study published by Turkish Association of Orthopaedics and Traumatology. The scientists studied the Triceps' muscle activity of the same motion at different angles. Here's what they found:
1. The long head generates more muscle force when the shoulders are at a 0-degree elevation (Arms to the side).

Target exercises/

-Dips
-Triceps Pulldown
2. A 90-degree shoulder elevation engages the medial head (Arms forward).

Target exercises/

- Bench Press
- Push-Ups
- Triceps Extensions
3. The lateral head creates more force when the shoulders are at a 180 degree elevation (Arms overhead)

- Overhead Press
- French Press
- Handstand Push-Ups
Everybody needs balanced triceps. Your workout strategy must include all three shoulder positions, whether you seek to build dense horse shoes on the back of your arms or improve your posture. Students of The Online School of Exercise maximize their results with these principles.
