The foam abdominal cushion offers you the opportunity to train your abdominal muscles with more comfort and stability. It isolates your lower, upper, and oblique abdominal muscles while simultaneously protecting your lower back due to its special shape. The Ab Mat is a popular product for a complete abdominal workout. The abdominal muscles can be trained at the end of the workout in a series. We recommend varying your abdominal exercises. During crunches, it is common for the lower back to become pinched during the lowering and lifting movements, which can lead to lower back pain. For this reason, this cushion is essential, thanks to its tailored ergonomics, to avoid such discomfort. The abdominal mat is lightweight and can be taken along when you train outdoors. This abdominal cushion is made from high-quality, firm foam that retains its shape even after years of use. The foam mat does not slip during repetitions. One size fits all.
