Not sure if the plywood itself could damage or mark the carpet but you could lay something thin down first.
Lifting platform on carpet.
This platform is not going to replace a dedicated olympic lifting or deadlift platform but it works just fine for protecting my custom wood floors from the occasional drop from a missed rep.
This won t go well.
In any case i consider it to have been well worth the time cost and effort it took to build.
Construction screws height will depend on thickness of platform 7 15 washers 3 10 oak spruce or other finer plywood for lifting portion 40 60 spray paint for logo 3 10 wood stain.
As mentioned above before my platform the only thing i had.
The hardwood has just the right amount of traction if you re using olympic lifting shoes.
The raised dedicated lifting platform is the ideal lifting surface if allowable in your gym.
A platform makes lifting safer in a few ways.
Most commonly a lifting platform is on top of the rubber flooring that s everywhere else in the gym.
Surprisingly it does save the carpet but it sucks to squat deadlift on and the weight has caused it to lift in places.
If you have anything but a concrete subfloor don t try a platform.
First it allows you to easily bolt your rack to a stable surface ensuring that it stays put during all your lifts.
Putting it directly on a concrete subfloor is fine.
