I'm currently on an abbreviated training routine.I hit chest once every 5-7 days.One exercise;bottom-position bench presses.I warm up with 3 progressively heavier sets of 5.Do 3 max singles using the same poundage for all three sets.Cut the weight back by 50 ibs, then do 3 sets of 5.Training for strength, I find 1 exercise performed with many sets to work well.I'd say my chest development is fair, but I'm not training for development, I'm training for strength.
