HOW: Place heels on elevated surface. Arms relaxed to the side. Apply pressure through your heels lifting your hips up. Once level, lift one leg straight up while the other stabilizes your body. Alternate legs up and down while maintaining elevated hips.
FEEL: Muscles in your core, hamstrings, hip flexors, and glutes should all be working.
COMPENSATION: Don’t let your hips drop down while alternating legs. Don’t twist to one side while one leg is stabilizing on the elevated surface. Keep your arms relaxed.
