The SMAI Ab Mat is potentially the most humble piece of gym equipment you can buy. With its simple design, the benefits of adding this to your workout are unparalleled. The SMAI Ab Mat helps lengthen out the spine, causing a longer lever and slight hyper-extension at the lumbar region (lower back) which then requires your abdominal region to work harder. Providing support and added cushioning to the lower back, its unique dimension and shape will snugly fit into the curve of your back avoiding any unnecessary strain. As a favoured piece of CrossFit® equipment, the Ab Mat won’t disappoint.
