Slow, heavy, to failure: strength training on a reformer.

[solidcore] cover

Founded in 2013 by Anne Mahlum out of her Washington, D.C. home, [solidcore] runs 50-minute classes on a custom reformer, driving muscles to failure through deliberately slow time under tension. Unusually for this shelf it is corporate-owned rather than franchised.

Why a Cadoo fitness game

The whole promise is failure on a machine that exists only inside their studio, so an off day is a total zero. A culture that already treats effort rather than a rep target as the win maps cleanly onto a form-scored game.

On our roadmap: redeem winnings toward [solidcore] goods and services. Not live yet. We’re building it.
