The thickly padded vinyl bench adjusts to 4 levels, and the footrest, backrest and thigh support all adjust to accommodate various user heights and workout intensities. Pivoting foam rollers hold your lower legs in place for hyperextension exercises and your feet for crunches. Folds for easy storage.
