That’s not really a thing, but we do always have check-ins every August and every February to kinda make sure “internet arguing muscles” aren’t the only thing forum members train regularly.
They also serve double purpose because, since they’re also six months apart, they can work as a kind of goal/deadline for anyone who kinda drifts along and trains without anything particular to shoot for. So like, “drop the waist two inches by the next check-in” or “squat 3 plates by the next check-in” can help keep people on track.
