You climb regularly and rigorously for exercise. Every day, like a substitute for going to the gym.
If this is the case, you are probably getting all you need for your lats, biceps, forearms, lower back, and maybe even abs. You can get decent, but not total, legs. And if you're aggressive enough, you can get a pretty good aerobic workout. But you have to be strong enough to keep it going. I dropped and kept off about 20 pounds climbing, while continuing to eat a fair amount of carbs and fat like peanut butter.
My lats and biceps are getting big, and my lower back is strong from all the thrust of DRT. My abs are in good shape, but I intentionally maximize their fatigue whenever possible.
What you don't get a lot of is triceps and pecs. Pushups or benchpress is needed, unless you do enough free climbing to use the pushup position.
It's also important to do range of motion exercise for your deltoids, because the motions of climbing (very much like rowing) leave out a large part of the upward and downward rotation of your shoulders. You need to work that or you'll feel some stiffness there, or even pain. I experienced massive pain, like a charlie horse in my shoulder, while aloft when I pushed down to apply pressure to a chain saw while my arm was fully extended. I was reaching full out with my arm while applying forceful downward pressure - well, I saw stars. My delt cramped up and it didn't stop for minutes. Taught me that I need some balance to what I'm getting in the tree.
