Lawrence and the Trainwreck actress took a note from the cheerleading handbook and formed a human pyramid with their other pals.
In the photo, Lawrence, 24, proudly shows off her toned body up top, hands thrown up in the air and a smile plastered on her face. The Joy actress wears a bright, printed bikini, shades and nothing else.
Schumer, 34, is positioned down below the star, providing support next to her friends as a pyramid base. She wears a grey shortsleeve shirt and also manages a big smile in the snap.
"Human pyramid," she captioned, simply.
