Hey dudes, I'm making a deadlift platform and I was wondering which of these two "designs" would work best. The main goal is to dampen sound but my gym is in the basement with concrete floor so I'd also like to minimise vibrations.
Please note that the sketches are in no way to scale and yes, there will be a thing in the middle to stand on.

Sorry for being an idiot, I forgot to mention:
The gray is rubber matting and the brown is construction grade plywood.

>> No.1150220

Damn fuck? Why not just lay down a single 4x8' sheet of plywood over a rubber mat or vice versa

>> No.1150221

>>1150220
Because I don't have that size of rubber mat and I don't wanna stand on rubber whilst deadlifting

Why not just try it before you make it permanent? Its all the same cuts, just different order.

>> No.1150226

>>1150222
That's actually a good idea, thanks. It will be a bit of work switching between them and listening for the differences but I'll have a definitive answer.

In practical terms, it's not going to make a huge difference, I think.

In theoretical terms, the alternating stack would be better.

Deadening sound is basically just a game of 'how much mass can I have supported by a damping material". The more mass you have and the more "loose" or de-coupled it is, the better.

But at the same time, in this case, you also want to decelerate the weights you're dropping on them as gradually as possible, which the second will be better at due to the increased thickness of the matting on top. Either way you do it, adding some thick foam padding (like those interlocking "puzzle-piece" foam floor pads) will help greatly for this reason.

Thanks man. The reasoning behing the alternating stacks was that the plywood piece in between the rubber was going to spread the impact over a greater area, allowing more of the bottom rubber sheet to absorb the force.

I've thought about using foam puzzle pads or carpet padding but I'm worried it will budge under the weight giving me an uneven surface

>under the weight
How much weight for 1RM?

Been there, done that.

Your solution is horse stable mats. For example:
https://www.horsematshop.co.uk/product-category/equine/stable-floors/

You can get ones that are close to an inch thick and they are usually cheaper than ones they sell specifically for gyms.

The noise problem wont be reduced because it is mostly produced by the movement of the bar + plates

You're worried about bulges when somehow you plan on deadlifting off of 2 tall stacks of wood and rubber. You sir are retarded. You start with the weight level with your feet FFS

>> No.1150270

Solution: Don't deadlift, you fucking idiot.
Do real weight training that is not about wannabe posturing.

Not him but deadlifting is one of the best ways to build strength in your core, lower kinetic chain and back. What's wrong with it?

this was my first instinct however i think the difference will be indistinguishable in comparison to adding another layer. are you that skint? carpet floor tiles like they use in offices are about 1 unit of currency each, kind of hard carpet shit on a layer of rubber. get a stack from a recycling place or something and tile a few layers.

This but just lay down two tires. Any tire shop will prolly give you some old ones for free.

Read the whole post you cunt. I didn't bother including the platform part in the middle because it wasn't important to the question.

Find a local facory or quarry or mine. Get free or cheap conveyor belting. Use razor knife and bend belting to cut to size / cut around fasteners. Dont make your fkoor with it without somhow coating it or melting a bilkion spots for traction. 1 drop of water and its ice. Good luck
