Made to be invisible.
koraiku keeps your plans, sessions and exercises in one place. You decide what to train and when.
How koraiku works
plan
A plan is your high-level structure. It groups sessions, keeps your order, and helps you stay consistent without forcing a rigid program.
session
A session is a focused block inside a plan. Repeat it when it fits your week, reorder it anytime, and adapt it as your goals or energy change.
kokori
A kokori is the smallest unit in koraiku: exercise, warm-up, mobility, or any intentional movement, with your sets, reps, rest, notes, and optional image.
