@deltabolic: If you sit with your body upright, you'll work the upper and lower glutes. If you lean forward, you'll shift the focus to the lower glutes (glute maximus). If you lean back, you'll shift the emphasis to the upper glutes (glute medius and upper glute maximus). Size & Shred Training program 👉🏻 deltabolic.com (link in bio) #hipabduction #hipabductionmachine
