@s.z.movement: fix this common mistake in side-lying exercises: You focus so much on lifting your leg as high as possible that you stop paying attention to your shoulder and waist position. Here's how to fix it: ▪︎First, move your shoulder away from your ear. ▪︎Then gently press your forearm into the floor and lift the underside of your waist away from the ground. ▪︎Only once you've established this position should you start moving your leg. You'll notice that your leg won't lift as high as it did when you were slouching, but the work will feel much more intense. That's exactly where you want to be! Focus on maintaining that position rather than lifting your leg higher.
