HOW: Find a step or elevated surface. Line yourself up sideways to the step and place your leg on it. Push yourself up and hold a single leg balance position.
FEEL: Keep your core and glutes squeezed as hard as you can to maintain your balance and to keep your pelvis level.
COMPENSATION: Do not let your hips/pelvis drop. Image a straight line across your hips or think about your pelvis being a glass and don't spill it!
