The KB Swing

When you think of what muscles the kettlebell swing works, your core muscles may not immediately spring to mind, but your core is just as important as your hamstrings, glutes and back when swinging. In order to maintain a neutral spine, your abdominals have to work very hard to prevent your lower back from rounding, and keep your head and chest high. Unlike sit ups and crunches, which emphasize spinal movement, swings train the core for what it’s designed to do – stabilization. There aren’t many exercises that will work your core harder than heavy kettlebell swings will.
