Duowheel ab wheel

Training with ab wheel offers not only strong abdominal muscles but also gives your core a solid workout. Not without reason, this ab wheel is often referred to as "Evil Wheel".

With the Duowheel you can train a minimum of space, and it is perhaps the toughest way of abdominal workouts you can make. The exercise can be performed on both knees, or on your feet if you are strong enough.
