Deltoids

"The three heads of the shoulder muscle — front, side, and rear."

Definition

The full breakdown. What it is, why it matters, how to use it.

The deltoid has three distinct heads: anterior (front — raises and pressing), lateral (side — creates shoulder width), and posterior (rear — supports posture and pulls). Balanced delt development requires training all three. Most lifters overdevelop the front delts from pressing and undertrain side and rear delts.

Q & A

Real Questions

Question 01

How do I build bigger side delts?

Lateral raises with controlled form, 10–20 reps, 2–3 times per week. Go lighter than you think — momentum kills the side delt.

Question 02

Do I need to train front delts directly?

Usually not if you bench and overhead press. Add direct front delt work only if they're visibly lagging.
