Ideas, by definition, are always fragile. If they were resolved, they wouldn’t be ideas. They would be products that were ready to ship.

We need a pull up and push up rig. The push up rig should accommodate push ups from 6 inches high all the way through 36 inches. And it should lend itself to inverted rows. 

It should also be able to accommodate 4 people doing pull ups at once as they perform pull ups at different heights ranging from 6.5 feet through 8 feet high. A few people might also anchor straps to it to perform assisted squats. 
 
It took five days of lathe work and machining but here we are on the final stretch but far from home. 

148 parts including 8 uprights, 2 flat bases, 2 X links, 4 fixed pull up bars, 4 adjustable row stands, 6 push up stands among other parts including bushes, nuts, bolts and threaded rods need to ground down, cut, chamfered and welded into a final product.

We are also using pick up trucks the way they were intended in Urban India :D
