Kathy Stevens says there are several features to look for when buying a high quality board. Don't buy a board that consists of two pieces held together with screws and bolts. In slide training, when you push off of one end of the board to the other, you hit the end ramp with a lot of power. You'll want to buy a board that will hold up well under the stress. They'll accommodate your body biomechanically as it reaches the other side.
Straight ramps place too much stress on the ligaments of the knee.
You'll realize the benefits of slide training only when you do it properly. If you buy a product with no instruction, it will probably sit under your bed, or worse, you'll get injured. Again, as with any other activity, proper technique on a slide board is essential to preventing injury. Here are some guidelines to ensuring proper posture and technique. You'll know you're standing at the back of the board if the end ramps are angled outward.
