Strength Conditioning Outlet

Excersize suggestions? Strength conditioning in particular.?

I am a former division 1 tennis player and am now in graduate school and trying to find productive outlets to workout (I am in still in very good shape I just get bored 'hitting the gym'). I have typically lifted weights and done cardio, all the standard stuff. I a lot of times get bored with the same old routines and wanted to change it up. Most of my lifting consists of a mix between free weights and machines. Does anyone have any suggestions that will help increase my strength or any tricks to stay motivated to keep wanted to drag myself to the gym?

Just think about going to the beach and seeing all those hot girls staring at you and talking about your hot body.... Go to the gym dude! U don't want to be the fat guy at the McDonald stand that people are making fun of.
