Kettle Bell Single Leg Ab Crunch On Bosu Ball

If you want to build up your abdominal muscles (for that 6-pack you’ve always wanted), you’re going to have to do more than just crunches. You really need to work those muscles and train them like you would any other muscle group. Adding some weight helps fine tune the results of your traditional ab workout. Using a kettle bell hooked to your foot and balancing on the bosu ball, you’ll engage and strengthen your muscles much more than a traditional bicycle or single leg -up exercise would. Try mixing this in to your regular ab workout using 4 x :20 rounds of work per leg with :10 rest in between. I a using a 13 lb kettle bell hooked to my foot.
