Shoulder Press, Push Press, Push Jerk
Katie has a really solid push press. Her dip is great, if you look at her 1st photo, her shoulders, butt, and heels are all in a nice straight line, allowing her to aggressively drive the bar off her body, through her heels, with no forward inclination of her chest, putting maximal momentum on the bar.
Lindsey was also a great demo today! Great push jerk. Nice dip and drive, solid catch through the shoulders, beautiful overhead position.
