Beating Seated Chest Press

Having hit 100Kg on bench, the next self-imposed challenge is to add on the three discs that increase the overall weight that I'm pushing. Each disc is 1.25kg each, hence pushing these 3 plus the 20 plates will equal 103.75kg. That's as heavy as the chest press machine goes.

I should be able to beat this within a month. Much less, in fact.
