Lifting Platforms (Mon 4/12/10)

I get a lot of questions about the new lifting platforms at the gym about what they’re for and why they help. Lifting platforms provide several benefits both to the facility and the athlete using them. For the facility, the rubber pads cushion the impact from the bumper plates when a load is dropped and help extend the life of the bumpers and the barbells. They also serve to protect the floor from an obvious beating. For the athlete, the wood provides a stable and incompressible surface to stand on in order to eliminate power loss during a lift. Think about it this way: which surface are you able to jump higher from – a soft sandy beach or one of the lifting platforms at the gym? The sand compresses as you jump and absorbs much of the power generated, resulting in a much lower jump than jumping from a hard surface like a lifting platform. True, the rubber mats at the gym don’t compress all that much and are certainly a better surface to lift on than the beach, but the wood compresses significantly less than the rubber and therefore maximizes the power you’re able to apply to the barbell.

Of course, this is all kind of a moot point if you’re wearing big squishy running shoes with 2″ air-cushioned impact-reducing hydraulic-controlled shock-absorbing soles while performing your Olympic lifts…
