Side Leg Slides: Using Gliders can help improve pelvic balance and stability, improve your core (back and abdomen), glute and leg strength
Beginners: repeat 3-5 per leg; only glide your leg out a few inches; do not over extend. Movements may feel small, but you'll feel them the next day!
Progression: increase your repetitions, glide your leg out further, glide your leg backwards and/or frontwards.
