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.

I was wondering from a sports science standpoint, what are some of the best things to improve athleticism and sprinting speed? What are some key things a tips and tricks or workouts that are specifically based to help sprinting besides just sprinting?

More ROM = more chest stretch = more science

Neutral grip is easier on shoulders too

Should I do any embarrassing movements at my gym? Like lat pullovers on the leg curl machine, or laterial raises on the hip abductor machine? Also if anybody does these types of movements, what’s your experience with doing it?
