Programs that include mobility
Warm-up, main lifts, and cool-down stretches — not an afterthought note.
Your overseer in the gym
Train smarter. Log faster. Progress honestly.
Kubjas is a personal trainer web app for programs, progressive overload, and stretch work — built for the minutes between sets, not another cluttered tracker.
Real progressive overload
Double progression, linear steps, and duration rules for holds. Transparent suggestions every session.
Gym-floor speed
Log a set in a few taps. Rest timer and plate math stay in reach mid-set.
Stretches as first-class work
Hold timers, L/R sides, and optional duration progression for mobility blocks.
