It would be amazing, if you could really spend just a few minutes a day on the abs machine to get a tight, toned and sexy waistline. The AB Coaster Tommy Trimmer is suitable for cardio exercise and burning calories, especially burning belly fat. It helps in trimming the tummy and flattening the tummy. Its also used to get a big buttock. AB COASTER Tommy Trimmer Big is about 22.3kg. You could have this as your only abdominal/core exercise. The seat disengages allowing the user to twist from side to side during the ride thus hitting the waistline as well. It's fun The whole family can use it, It's well built, It really works, It engages the user so they will actually continue to use it. Safe, no pulling on the neck etc.
