Spire: Climb the Tower

Spire turns the weights you lift into one honest rank. Pick a benchmark lift for each of six muscle groups and train. Your best set of 10 reps or fewer becomes an estimated one-rep max, scored against strength standards for your bodyweight. Six group ranks average into one overall rank, E through A, across fifteen floors of the tower. Every floor is earned, and the climb only counts what you can lift today. YOUR RANK IS THE WHOLE POINT, AND IT'S FREE No subscription stands between you and your rank. No coins, no XP to grind, no streaks to buy back. The only way up is to get stronger. THE TOWER See your floor, how close the next one is, and which muscle group is holding you back. A body rank map lights up front and back, group by group. Weekly consistency sits right on top.
