These are a standing version of the Lying Hip Abductions (aka Side/Lying Leg Raises or “Jane Fondas”).
The standing version engages more core muscles as you balance on one leg.
Stand on one foot. Maintain tall and straight body position.
Squeeze medial glute (side of hip) to abduct (move away from body) as far as you can. Return leg to midline in a controlled manner. Repeat.
Perform 1-5 sets of 8-12 reps per leg. Or, perform 1-5 sets of 20-40 second intervals (doing as many reps as possible during those intervals).
