This versatile 2-in-1 ab trainer combines both an ab roller and a crunch machine, ideal for fitness enthusiasts looking to burn fat and improve overall health. The easy-to-use side knobs allow you to switch between the two functions: use the ab roller as handlebars in crunch mode or detach it for independent use as an ab roller. The ab machine features a TPR non-slip mat for added safety and an ergonomic figure-eight kneeling pad for better knee support and comfort. It offers 3 adjustable height levels and 2 angle settings to suit your workout needs. With 3 smooth, quiet metal rollers with bearings beneath the seat, the abdominal trainer ensures a smooth and noise-free operation. The built-in electronic display tracks key data such as time, count, total count, and calories burned, and even includes a convenient phone holder. The exercise equipment is foldable for easy storage.
