I wished to point out a pretty good tip a picked up a few days back. And this is about GTG and cycling.
While TNW's routine is terrific, it runs with the problem that one would tend to "burn" out. Nothing works forever, and GTG is not an exception.
However, a very useful way of using GTG is to pick an exercise that is very difficult (and you can only perform a few reps on), GTGing it, and then switching back to a more traditional routine of 2-5x2-5, 2-3 times a week. The GTG serves to bridge the gap, so to speak. It helps you build up your max to 3-4 reps, which will let you add it as a normal strength exercise in a routine.
Personally speaking, my problem came with One-arm Chin-ups. Doing them unassisted only yielded singles. Using a pulley to increase the volume didn't seem to have a meaningful carry-over (probably because the pulley allows the body to shift to the assisting side, while the OAC requires the pulling arm to be right at the middle). What I did was to GTG one-arm Chin-ups for a while.
And this worked better than expected. My max went to 3 per side, and now I can do 3x2 twice a week. This way, I can now practice One-arm Chins hard, but not have to worry about getting a bar 4 times a day.
Hope this little simple tip will help some Calisthenics-users to pick really difficult moves and add them in their training. It isn't very different from Consolidation Training. I just wished to show that it can be used with non-CC programs.
