A stable core helps reduce risk of injuries, and also improves posture as it helps maintain optimum spine position. Unlike other work out routines, the core slider engages various muscles to help prevent muscle imbalance. A strong & stable core can also help alleviate lower back pain. VERSATILE TOOL - Use for a variety of workout routines, including yoga, pilates, aerobics, conditioning, amongst others. Since your feet or hands never leave the floor, core sliders allow you to strengthen and tone your body, glide into lunges, planks, hamstring curls and push ups without putting strain on your joints and tendons. DUAL SIDED - Our core sliders have a diameter of 17.5cm and are ideal for use on hard floors or carpets. Use the coarse side for hard floors and smooth side for carpets. LIGHTWEIGHT & PORTABLE - Includes a convenient carry bag, to take with you to the gym, while travelling or store neatly when not in use.
