I used to be pretty out of shape after I stopped playing hockey after college (which I played my whole life). Then I started to lift about 1 1/2 hours a day+cardio. Sex was one of the reasons why I first started this.
And not to get too much off topic, but traditional benching is overrated. I prefer using dumbbells for chest presses instead, and nothing beats doing flies...well almost anything...

Well, I plan to compete in Bench for Power Lifting. Also, I don't just do Barbell Bench, I do these for Chest Day, but not on the same day of course lol:
Barbell Bench Press (Standard/Inclined/Declined)
Dumbbell Bench Press (Standard/Inclined/Declined)
Dumbbell Flies
Cable Flies
Tricep Cable Press (Horse Hair, Single Bar, Double Bar, etc)
Shoulder Press Machine
Barbell Military Press
Dumbbell Military Press
Barbell Standing Shoulder Press
Dumbbell Standing Shoulder Press
Push Ups (Weighted/Perfect/Inclined/Declined)
Usually I do 3-5 different exercises per body part, and 2-3 body parts per day. Example:
Chest/Triceps/Shoulder Day
Gym
Chest: Barbell Bench Press (Standard) (5-8 Sets)
Chest: Dumbbell Bench Press (Declined) (3-5 Sets)
Chest: Dumbbell Flies (3 Sets)
Triceps: Tricep Press (Horse Hair) (3 Sets)
Triceps: Tricep Press (Single Bar) (3 Sets)
Shoulder: Barbell Military Press (5 Sets)
Shoulder: Cable Flies (3 Sets)
Home
Perfect Push Ups (3 Sets)
Weighted Push Ups (1 Set)
Push Ups (5-8 Sets)
I weight lift mostly cause it makes me feel amazing, but also, being 5"5 and having all friends nearly 6"0+ who are all trying to be "strong" makes me have to compete. I take pride knowing I can out press most people I meet, even if its just because I am so darn short lol.
