Beginners vs experienced trainees

In this episode, I talk with fellow YouTuber Jeremy Ethier about a new study that he co-authored that compared muscle growth when training with more tension in the lengthened position versus with more tension in the shortened position. We'll cover what these new findings mean, if this changes our thoughts on "the stretch", and how these findings should be applied to training.
