How to Easily Build a Lifting Platform (and the EASIEST way to cut stall mats)

A lifting platform is a very important part of your gym - it protects your equipment as well as your floor, it dampens the noise and vibrations of deadlifts, cleans, snatches, etc., and it clearly delineates the lifting space. This last factor - the abundantly clear “stay out of my lifting space” effect of the platform - is very useful when you have a training partner or little kids with you in the gym.
Fortunately, building a lifting platform is quite easy. In fact, “building” is a rather generous term for the process - we’re pretty much just assembling a platform. We’ll lay out the steps below, but I’d strongly recommend watching one of the videos linked throughout this article for a better understanding of the process.
First, lay two 4’ x 8’ sheets of OSB next to one another. I’d recommend what is commonly referred to as 3/4"-thick OSB, but the actual dimension will be listed as 23/32”.
Laying down the base layer of OSB sheets
These two sheets will run lengthwise, i.e., they’re run front-to-back. The sheets will probably have a slight bow to them (i.e., a curvature), and you’ll want to make sure that the crown of the board is up (so the board should make a mountain, not a valley).
Next, lay two more sheets of the same OSB on top of the base layer. These sheets will be perpendicular to the base layer sheets, so they’ll run side-to-side. Again, the crown should be up. Then you’ll use 1-1/4” screws to attach the second layer to the base layer. We use three screws on the short end of each board and four screws along the long end.
Laying down the 2nd layer of OSB sheets
Then, for the top layer, you’ll use a sheet of 3/4”-thick MDF to run down the middle. You could use something nicer like oak, but we like MDF as it’s nice and heavy and causes everything to lie nice and flat. You’ll need to do some cutting on the MDF as they are sized at 49” x 97”. You’ll cut the length to 96” (8 feet), and we recommend cutting the width to 42” (3.5 feet) as this gives you ample room between the plates and the MDF when you set down your deadlifts, cleans, etc (you can go with 4 feet wide, but 3.5 feet makes it much less likely that you’ll chip the MDF over time). You can do this yourself, or your lumber store may be willing to rip it for you.
Finally, you’ll use 3/4”-thick horse stall mats for the rest of the top layer. Stall mats are typically 4’ x 6’, so you’ll have some cutting to do here. The bigger piece on each side will be 72” x 27” (i.e., 6’ x 2’3”), and the smaller piece on each side will be 24” x 27” (i.e., 2’ x 2’3”).
To attach the top layer to the second layer, use 1-5/8” screws. We put six screws into the MDF - three in front and three in back. For the stall mats, we simply put screws around the outside, front, and back of the platform - we don’t put any screws down the rubber edge near the MDF so that we can’t accidentally set our metal plates or bumper plates down on a screw that might be a bit proud.
Last note - when cutting stall mats, use a jig saw. It is - by far - the best way to do it. Check out the video above to see this process.
We hope this helps you quickly and easily build a lifting platform, and as always, we hope this helps you get stronger and live better.
