With multiple abdominal machines in our facility, including, the AB Coaster, Hoist Roc-it, Cybex VR3 & Nautilus Ab Crunch, the EXT3 by far is the most popular and most effective! Based on the overwhelming demand for its use, I will definitely be ordering more units! Simple to use, highly effective results and its comfortable design makes this product a real winner!
