I've been revisiting the old low impact program that was sold as a PDF and wonder if it and the others that were being sold around that time could be republished as their own calendar challenge. I recreated it as a custom routine and took my liberties with a few of the repeated exercises or when it would say 'x minute independent warmup', but could be a fun thing to have available and be 'official' to users. Maybe could be a fun 'old school' perk program to free users too. I know the focus is on newer videos, but just an idea (～￣▽￣)～
