2x8 beam and approx 4x3 posts. Not 4x4 as they are around 3x the price as these landscaping timbers but only 20 percent more strong approx.

I put my model in a structural calculator. Bench is 10ft long.
Each post has a compressive strength of about 5000lbs and each beam can handle 1000lbs uniform load distribution with a very small deflection that meets code for floors.

Remeber when building, if you double the span of a beam, the strength decrease proportional to its cube, so it becomes 1/8th the strength. I tested it out for the 2x4 shelving below. I got the 10ft 2x4 to deflect with my 130lb me in the center about an inch. I put a little wood cut off to support in the center to reduce span to 5ft and I have it loaded with around 300lbs of crap and it has no deflection.
The posts have half lap joints as if it was screwed it would fail easy under load. The top is open no plywood as tools are stored there.
Later there will be a fence for the miter saw and little planks on bolts so that the miter saw had a little outfeed indeed table that can be adjusted for coplanar without ruining my open shelving for tools.
See that little block in the last picture, that just 8x the strength (1/8 the deflection) by cutting the span of the 2x4 in half.

Yeah, now today, my garage looks a lot messier than than picture yesterday.
I also got a free concrete mixer. I think it looks like a giant mortar/cannon which is pretty sick.
Basically, i brought my bike and the wooden trailler about 5 miles to his house and was gonna strap tie it down and bike the beast back home.
Well, he originially wanted 100 dollars for it, but he said i can have it for free if i helped him with some yard work where i dug out some concrete pillar things which had poles in them. Then he drove the mixer back to my place for free. Really nice. He also said he was moving and gave me a bunch of plumbing stuff like solder and sparkers and stuff and some other stuff. Said he would also give me an old car of his if i got it to pass emmisions because he was leaning toward scrapping it. He said the old car failed emissions even though he put in a new catalytic converter? That doesn’t make sense. Said fixing it would cost more than the cars value.

You’ve got to have a strong bench, if you notice the bench is made of warehouse racks. I worked 34 years in a distribution center and got a lot of salvage.
 
My workplace is so small and so crammed full of stuff/junk/stuff/junk it's more like working in a obstacle course than a shop. I like that organized chaos. Especially when I find something cool that I forgot I bought.
