Floor presses are normally used as a max effort exercise. I'm starting to shy away from heavy singles on a lot of exercises because I feel like too many singles were just not effective. I'm liking heavy triples and sets of 5.
Floor press: warm-up, 185x3, 225x3, 315x3, 365x3, 405x3, 455x3
or work up to a heavy set of 5 or even 3 sets of 5 if you are trying to build some mass.
Triceps work
Upper back work
Delts
