Utilizing the correct muscle groups during the arm recovery can help every swimmer create a more relaxed and smoother movement through the recovery.
A swimmer that users their traps and posterior (back) deltoid will generally do a number of things wrong at the back end of the stroke
- Finish short at the end of the stroke with the arm following the body rotation
- Pull their elbow over their back to start the recovery generally creating an over rotation of the upper body
- Low profile during the arm recovery (flat arm recovery)
- The arm will generally swing from over their back to across their front for the entry (cross over at the front of the stroke)
A swimmer that uses their pectorial and anterior (front) deltoid will create a strong smooth recovery movement because
- They've separated the arm recovery from the body rotation
- Can create height by pulling the elbow up
- High profile through the arm recovery
- Forward movement of the arm creates at clean entry around the optimal position - shoulder width apart.
