Push-up with Side Plank

Starting in the full plank position with hands directly below shoulders, perform a push-up being sure to engage the triceps by tracking elbows back rather than outward. Once you've returned to plank position, stack or stagger feet and rotate outward to perform the side plank. Hold for 5 seconds, rotate back into push-up position and continue with another push up. Alternate sides after each repetition.
