Functional fitness

I've been rehabbing a groin pull and at my last session, I asked my physical therapist what his workout routine was. He said he does Olympic style lifting and body weight stuff (pushups, pull-ups, planks, etc) several times a week. He emphasized that he believes in "functional fitness." He said that a lift like the bench press is not a good exercise because you would never do anything like that in real life. The only purpose of the bench press is as a measurement of upper body strength, so you can compare to other people.. He thought that the true measure of fitness is: "can you pull a person out of a burning car?"... "if you're dangling off a cliffside, can you pull yourself up?" He's a huge fan of pushups (instead of the bench press). He also really likes squats and deadlifts, which work the posterior chain. I asked him about the TRX and he said it was a useful device because it allows you to work out your back, which is hard to do in bodyweight exercises.
