If you’re ready to take the classic wall sit to the next level, try adding a resistance band around your thighs while opening and closing your legs. Also known as a banded wall sit with hip abduction, this variation targets more of the smaller muscles in your glutes, and with the right focus, it recruits your pelvic floor muscles.
Strengthening your pelvic floor muscles is important for a variety of bodily functions, says Monica Saliu, DPT, cofounder and clinical director of Tribeca Physical Therapy. For example, your pelvic floor supports your internal organs and helps with bladder control, bowel movements and sexual function.
