About the same like the Humping Dog/Exercise Dog, the Kinniku Man (Muscle Man) will teach you how to get six packs. Plug this Kinniku Man to the USB and it will start doing non-stop sit-ups. Yup that’s up, no other function and no storage. Choose from Kinniku Man, Robin Mask, Wars Man, and Ramen Man. One will cost you $34.
