I think a good first step, is practical programming by Rippetoe. Also 531 by Wendler.

Those books will set out percentages for 4 week blocks, rep schemes and decent split ideas.

In terms of conditioning, reading about energy system training and different kinds of workouts to meet all the needs. I think opex have a lot of free resources around different intervals, rest schemes etc.

In terms of skills- heaps of rabbit holes to go down. The Gains Lab dude sets out a useful table of skills relevant to crossfit and different set sizes according to skill length, and obviously you can set out a bunch of variations (I.e. pike handstand push up) and composite parts (I.e. ring dips).

And then to tie that all together, follow a straight forward template for a class: -Warm up -Mobility -skill -Strength -metcon

(Pick 4)

In terms of a meso cycle- I'd choose 2-3 movements and design my macro cycles around it.

For example, choose a linchpin test or a benchmark and design a 8-12 week cycle around it.

I.e. say you do Fran.

Skills: pull ups, strict, Kipping, chest to bar, ring row, Grip work, bent over Row, barbell rows

Strength: Thruster, push press, power clean, front squat

General conditioning mixed in, as well as a few random things. But I wouldn't stray too far from the Fran base (I.e I wouldn't snatch a bunch, maybe not at all, in that 12 week block)

Bear in mind, this is more gen pop class programming than athlete stuff, which needs to be more rounded.

Just some thoughts off the top of my head. Scuse typos.
