The BOXPT Equipment Abmat is an essential accessory for your core workout. It allows greater efficiency in performing sit-ups and crunches through its rounded outline. While exercising the Abmat allows you to stabilize the pelvis as you contract the core, reducing discomfort in your back and avoiding the risk of injury. When using the Abmat in core work, it will help achieve a much more complete muscular workout: of the abdominal, oblique and lumbar muscles.
