This could be cool or it could get pretty murky with lift verification and consistent form standards. Either way, definitely worth a shot. Like the T-ransformation challenge, it’s great that this is something you guys are coming up with on your own.
It seems like the easiest way to look at it is something like, “Everyone has until Jan 7 to post a vid of their heaviest squat single, heaviest bench single, and heaviest deadlift single.” Basically leaving it open for people to treat it like a 1RM test week instead of trying to do a mock PL meet all in one workout.
I’d also suggest a snapshot of the scale’s reading at weigh-in (not necessarily of your physique, of course). The honor system is totally fine, but I feel like it’s too open to “I weighed around 205 last week after dinner, so I’m probably closer to 198”. Especially if you’re going off Wilks, it seems like the most accurate way to get a bodyweight.
