I'm big on avoiding switching movements, people get the bodies adaption confused as a bad thing. Stick to the same movements and progress in weight and reps, the body becomes more and more effective with it and will continue to improve.
Switching movements is more for mental stagnation.
We lift weights and manipulate our diets so that we'll look good naked. Sure, it's healthy too, and we'll probably live a longer and more productive life than the average guy, but mostly it's about the naked thing.
