Building a Bench Press

Rather than paying a lot of money for some third rate gym, I’m thinking of designing and building my own bench press.

I’m thinking of using a bulky wood design for safety. Most of the work would probably in assuring the weight stand can support 200lbs. Also finding some place that has a good deal of heavy rocks for the weights would be good too.

Anybody got any suggestions?

If it goes well I might try to sell them on ebay. LOL
