Kayla Itsines' 28-Minute Total-Body Workout

Start by placing your forearms (wrist to elbow) on the floor and extending both of your legs behind you, resting on the balls of your feet (A). This is called a plank position. Release your left forearm, and place your left hand firmly on the floor directly below your left shoulder (B). Push up onto your left hand, followed immediately by your right in the same pattern (C). Ensure that you brace through your abdominals to prevent your hips from swaying. Return to plank position by releasing your left hand and lowering onto your forearm before doing the same with your right hand. Repeat this exercise, starting with your right hand. Continue alternating between right and left for 24 reps (12 per side).

Plant both feet on the floor slightly farther than shoulder-width apart (A). Carefully take a big step backward with your right foot. As you plant your right foot on the floor, bend both knees to approximately 90 degrees, ensuring that your weight is evenly distributed between both legs. If done correctly, your front knee should be aligned with your ankle and your back knee should be hovering just off of the floor (B). Extend both knees, and transfer your weight completely onto your left foot. At the same time, lift up your right foot and bring your knee in to your chest (C). Release your right leg from your chest, and place it back on the floor behind you. That’s one rep. Complete 12, then switch sides and do another 12 reps.

This is called squat position. Propel your body upward into the air. Extend and reposition both of your legs to land in a lunge position, with your left leg forward and right leg back (B). Ensure that your weight is distributed evenly between both legs. Immediately propel your body upward into the air again. Extend and reposition both of your legs to land back into squat position (C). Immediately propel your body upward into the air again. Extend and reposition both of your legs to land in a lunge position, with your right leg forward and left leg back (D).
