Review on Hockey Revolution Adjustable Length Training Tiles Sliding Board: Enhance your hockey skills with this innovative training tool by Ralph Gerry

You really can get a hockey style workout and a ski style slider. Lay this on a hard surface, you can use a thin dense rubber mat to reduce movement of the whole setup. Or use the included mat on a hard, flat surface. Carpet is not a good idea - it allows the seams of the tile to move and change height only slightly to keep your foot from slipping. Dude, you're talking about cardio, but you can walk at a comfortable, steady pace without hurting your back or knees or overexerting yourself. It glides really well. No doubt. You get what you pay for. The best I've used.
