Built for the gym floor
Weight, reps and reps in reserve on controls big enough to hit one-handed. The rest timer starts itself the moment a set lands.
Costia TrainingComing soon
Log the set without leaving the rack.
You open it, you log the set, you carry on training. It works with no account at all: install, pick a routine, start logging.
Coming to iPhone, iPad and Android
Routines that fit you
Push / Pull / Legs, Upper / Lower or Full body — or four questions and it adapts one to your days, time and kit.
A history, not a number
Estimated 1RM per lift, tonnage per week, sets per muscle against a target band. Progress is a line, not a figure that keeps being overwritten.
What to lift next
Repeat until you hit the target reps, then add one step. Deliberately dull — and every suggestion can tell you why.
