Start standing with your feet hip-width apart. Your chest should be lifted and core pulled in toward your spine.
Bend your right leg, bringing your knee up towards your chest. Lower your torso slightly towards your knee, but keep your back flat, chest lifted, and core engaged.
Step your right foot towards the right and take three quick, lateral, high-knee steps in that direction.
After the third step, pause with your left leg bent and torso slightly lowered.
Repeat in the opposite direction, moving three steps laterally to the left until you return to the starting position.
This counts as one rep. Do as many reps as you can with proper form for 30 seconds.
