By supporting your lumbar spine and eliminating space between your back and the floor, the AbMat increases stability while isolating your abdominals for a total core workout. With the AbMat positioned beneath your spine at the start of a sit-up, you get a full stretch of your abdominal muscles, which is impossible to obtain on a flat surface. As you rise, your pelvis is supported, allowing your muscles to fully contract and resulting in a more thorough and effective workout. Proudly made in the USA, the antibacterial, single-mold, closed-cell foam construction makes AbMats durable and easy to clean. The textured surface and non-skid base let you confidently pursue your workout goals because the AbMat will stay firmly in place. No more relying on momentum to do your sit-ups or risking injury from lack of support, the AbMat enables complete range of motion for total core conditioning. Durability meets necessity in this complete core workout tool.
