If you’re bored of crunches and looking for a new way to up the intensity of your next ab workout, we’ve got a simple fix — raise your legs to the ceiling. Vertical leg crunches are a crunch variation that helps you target more of the muscles in your mid-section.
While the basic crunch targets the rectus abdominis, or the outer six-pack muscles, the vertical leg crunch also targets the deeper transverse abdominal muscles, the internal and external obliques, and muscles in the lower back.
