Even if I wind up spending months studying existing designs, sketching out and thinking through my own designs, there is absolutely no substitute for repetitions done on a prototype or final product.

However you think or simulate that it will feel, the feedback will be unlike anything you could imagine. 

Here I am playing with our new back extension machine. Trying to figure out the ideal thickness for the pads that the thighs will rest on. 

And it feels terrific. The machine as expected complements our existing parallel-to-floor back extension machine perfectly. And it also betters what’s available by being much more nuanced on the support it provides for the lower body. And the grip of that chequered plate is just (chefs kiss) great.

Anyways time for more reps to finish this job.
