The ABS Discs are a great tool for building up your core. The surface is slippery and all the motion is controlled with your abs. You can use this on any smooth surface.
Incorporate this into your regular abdominal routine. I would recommend 4 sets of 25. The slower you do them, the better it is for your abs.
Bonus: Use this to hold a plank. The discs will make the plank harder and more muscles will be activated while the intensity is increased.
