How to Understand & Train the Triceps Brachii – Treadwell, DPT Anatomy Breakdown
Here we go — Treadwell, DPT back with another Anatomy Breakdown – Muscle by Muscle.
Today we’re breaking down the Triceps Brachii, the big 3-headed extensor of the upper arm. This muscle makes up about two-thirds of the upper arm’s mass — huge for pressing power and functional pushing.
In this video you’ll learn:
𖤓 Origins and insertions of the long, lateral, and medial heads
𖤓 Primary and secondary functions (elbow extension, shoulder extension and adduction)
𖤓 Innervation and key nerve roots (radial nerve, C6–C8)
𖤓 Clinical and training insights for rehab, wheelchair propulsion, crutch use, and hypertrophy
𖤓 EMG and MRI research on head-specific activation, shoulder angle effects, and grip variations
💡 Key Research Mentioned:
– EMG studies on triceps head activation at different shoulder angles
– MRI study showing greater long-head hypertrophy with overhead extension training (12 weeks)
– Cable pushdown grip variation study (supinated vs pronated for long-head activation)
