Comment “PURE” to learn how to keep your lead arm straight and stop it from breaking down in the

Golf instructor Rob Cheney breaks down why the lead arm collapses during the backswing, citing trail arm over-flexion and lack of shoulder rotation as the main culprits. He demonstrates how to maintain swing radius by pushing the trail arm away and properly retracting the trail shoulder to prevent common misses like tops and chunks.

• Push the trail arm away from the body during the backswing to prevent it from over-flexing and pulling the lead arm into a bend.
• Lack of trail shoulder retraction limits rotation, forcing the golfer to bend their arms to create artificial swing length.
• Bending the arms at the top of the swing compromises the swing radius, leading to inconsistent contact.
• Sufficient body rotation is the mechanical requirement for keeping the lead arm straight without tension.
