The bigger issue here is that these events are written assuming you bought everything, so the main book literally cannot stand on its own. You skipped issue 3 of the tie-ins and suddenly the hero has a magic sword nobody explained. That is a writing problem, not a reader problem. People defend keeping up because the books quietly punish you for not doing it, and then everyone blames the guy who quit instead of the folks who built it that way. Your regular has it backwards.

Learning the "Savage" dance from my cousin took me maybe 15 minutes and the moves are way easier on the knees (mostly arm stuff and a little bounce, no deep squats). The "Say So" one is another good starter since it's just a lot of hip sway and hand motions. Stay away from anything with a lot of floor work or jumping splits unless you want to ice your whole body after. My rule now is if the kid teaching me has to sit down to catch their breath, I'm out. Retirement is for quitters, just pick the low impact ones.
