There are so many reasons to love the rotating deadlift, but the fact that you can do it anywhere tops our list — convenience is the mother of bodyweight exercises. Deadlifts are great for strengthening the butt and toning the hamstrings, and adding the twist focuses the core work on the obliques to tighten your waist. With your hands placed behind your head, not only will the abs be forced to work harder, but this position targets the upper back to improve posture and reduce neck pain. So many benefits in one simple move.
