Casey Counts | Muscle & Mobility on Instagram: "THE FORM: • controlled eccentric • lean back slightly at the bottom of the rep • stand straight when barbell is overhead • chin slightly up on the eccentric These involve explosivity out of your end range, while maintaining maximum tension.

This will not be good for your shoulders if you go too heavy.
