With weights in hand, lower weights to the ground and hop feet back into a plank position. Next, hop your feet to meet the weights and rise to standing. As you stand, press the weights overhead with palms facing each other. Lower weights carefully to your sides before getting back down into plank position. During all parts of this movement, make sure that knees are in line with ankles, shoulders in line with wrists and your back is neutral (no dipping toward mat). Repeat as quickly as can be controlled.
