Step by step instructions
From plank position, lift hips up and press chest toward thighs so body resembles an upside-down "V," pressing heels as close to floor as possible. (Bend knees if needed.)
Engage abs and quickly shift back into plank position. Immediately lower into a triceps pushup, bending elbows in by sides and lowering body as close to the ground as possible. (Modify on knees if needed.) Return to start.
