Then just omit the incline execises - they do work the upper chest but you can get by with just the flat presses and flyes.

p.s. the circuit would be for the abs only - take your time with the chest and other exercises until you've perfected your form. I would suggest doing the first set of the first exercise, resting 45 secs and then doing the second set, resting 45 etc. Do each exercise then move to the next one and rinse, repeat.
