HOW: In a standing position, shift most of your weight to one leg and bend that knee as you bring the other leg behind you in a diagonal motion. Once you can not reach behind you anymore, push into the ground with the bent knee and propel yourself laterally into a jump and land with both feet. Perform that all in one controlled motion.
FEEL: You should feel your leg muscles working.
COMPENSATION: Keep your chest up as you perform the curtsey lunge.
