+# Dip
+
+The bodyweight press on parallel bars — lower until the shoulders reach
+elbow depth, then press back to straight arms.
+
+- **Category:** Main circuit
+- **Type:** Bodyweight elbow extension (chest/triceps press)
+- **Targets:** Triceps, chest, front delts
+- **Prescription:** 3 × 6–12
+
+## Setup
+
+Support yourself on the parallel bars with straight arms, shoulders
+pressed down, slight forward lean, knees bent behind.
+
+## Execution
+
+1. Bend the elbows and lower until the upper arms reach parallel.
+2. Keep the elbows tracking back, body leaning slightly forward.
+3. Press back up to full lockout without the shoulders shrugging.
+
+## Cues
+
+- Shoulders stay down away from the ears at every depth.
+- More forward lean hits chest; upright hits triceps.
+- Depth to parallel — a shaky bottom inch isn't worth the shoulder.
+
+## Common Mistakes
+
+- Sinking the shoulders into the ears at the bottom.
+- Flaring the elbows straight out.
+- Bouncing out of the deep position.
+
+## Progression
+
+Use the assisted dip machine or bands until full-range reps are smooth;
+then add reps, then hang weight from a belt.
