Functional? When will I ever be laying down and need to lift a weight over my head and try to get up without using my other arm? This sounds like a skill only a retard or a cripple of some sort would need to master.
I'm 100% certain you could easily master the turkish getup.
At any rate, what's your point? It's equally unlikely you'll be asked to do leg presses, cable curls, triceps pushdowns, diet or pose for hours on end anytime soon.
I realize you're too far gone for reasonable answers but someone else may actually be helped by this response. What use is looking good when you can't lift or do shit?
Have you ever seen a bodybuilder help someone move or or do actual work for more than a few minutes versus a powerlifter, or anyone who trains for functional fitness? I see fat fucks and twinks all the time working like crazy on the lat pulldown who can't do a single chin-up, LOL! Or the same guys will load up the angled leg press, make all sorts of noise but can't even do 30 or 40 full bodyweight squats, LOL!
Exercise should increase a person's function, health and overall fitness. Otherwise there's no point.
