seat width... please tell me.

Can anybody measure and tell me the width , of the pad that you lay on when doing benching , incline benching , etc...

you should make it custom to your shoulder width. Id measure from rear shoulder joint to rear shoulder joint.

take in consideration that you will grow wider. So make the bench easy to modify the pads.

K cause I want something that will have full range of motion without feeling like the pad is in the way , or too narrow.

Sounds like a good idea , It basically im thinking is going to be 2 by 4 , put together with a brace on the bottom which catches the PVC .. hopefully the picture is easy to imagine..

can always add another 2 by 4 because the bottom brace doesnt have to be same width as the seat , that way I can add width later. But alot of people all shapes and sizes.

They use the same dimension seat in the gyms with easy... that what I was thinking that size would work.
