Wow! The heavens moved into alignment and we have the Perfect 3 guys to think our way through this!
At the risk of stereo typing, 1 guy is a ninja warrior athlete, one a strongman and one a powerlifter.
Classic western or linear periodization goes from high volume/low intensity to low volume/high intensity. Lots of light work to less heavier work. As chris mentioned, block periodization is often just like that. This works for powerlifting. Tons of volume for muscles then later get good at heavy lifts.
Louie and the conjugate guys call this a De Training system. You do less work over time. This won’t work for the ninja warrior. It would be silly to cut volume of the skill work just to lift heavier weights.
A strongman can’t get stronger and do less work as the event get close. Ideally they would start out strong enough, and then get more reps or go faster Or last longer.
If you need more skills or more power/speed/endurance you can’t do less work and less volume. Westside dudes keep the volume and intensity and work load super, super consistent week after week. They also keep it continuously creeping up week after week after week. Like strongman goals mentioned, they accomplish this with exercise variation. Strongman and athletes are always inadvertently changing exercises as the competitions/events/conditions change. More variety makes them more skilled.
Dave Tate talked about this way back in the first TNation article I ever read.
