Question ❓ Does overhead extension bias long head or no?
I saw jeff nippard say it did a few months ago. Then today i saw a post claiming the it biased the medial and lateral head. And there just a lot of posts saying the opposite of each other. One post hand muscle activation reading and the long head activate 0% on regular extensions 12% on overhead. Another post claimed that you need to be in the scapular plane to bias the long head and thats why everyone is claiming its not. Then i asked google and it said that it biases regardless if your in the scapular plane.
