I absolutely love using the work outs and programs from Darebee.com
Years ago they did nerd orientated workouts, like Batman or Wonder Woman, Vikings, etc. but they got a cease & desist most likely.
And yet they've kept going, releasing well thought out programs and routines, for varying skill levels, with alternatives for different health levels or abilities.
All for fucking free. No pay wall, no pay to access, or premium levels, memberships. Just free.
