Hi. I am coaching a friend through the Olympic lifts. He lacks a lot of flexibility in the pecs, lats, shoulders and worst of them all biceps.
His overhead squat is improving due to a lot of chest stretches however the biceps is as rigid as ever.
Any suggestions on how to give him an inch extra of lockout would be so helpful. He is strong as hell but it is pretty hard to hold 100kg with bent arms.
Example of problematic lockout. It was a PR but still very risky.
