I built my deadlift platform to be both movable and expandable. For the base, I used a single layer of 1/2” plywood. After about three months of heavy use, I’ve had zero issues with it—mostly because the entire gym is already floored with 3/4” horse stall mats. For the top layers, I used 3/4” sanded plywood for the lifting center and 3/4” horse stall mats for the drop zones.
My primary goal was to save space and ensure I could easily pick up and move the platform when I'm not deadlifting. Because the three sections don't have to be permanently interlocked, I also have the flexibility to expand the overall length of the platform… just in case a specialty bar longer than 7 feet happens to make its way into the gym.
