How to do Hawaiian squats
Begin standing with the feet together and your arms down at your sides.
Shift all your weight into one leg as this will be your working leg. With the other leg, lift it up off the ground and cross it over the working leg in a figure-four position.
Now perform a squat on your one working leg as you lower the hips down and back. At the same time, reach straight arms forward until they are parallel to the ground. Squat down until the hips are below the knees (if possible).
Then, stand back up as you straighten the working leg completely and lower the arms to your sides.
Repeat for the desired repetitions, on both legs.
