How the tree works
A node opens only when you pass its challenge: a timed hold, a number of clean reps, or landings out of attempts. Quality you can only judge by eye, such as a straight line or a clean exit, is self-assessed. Practice volume, gym numbers and the coach's opinion never open a node.
Practising a node in Kufu logs a real workout: a short warm-up, the node's drills and a cooldown, on the iPhone or the Apple Watch.
What it builds
Lats, core and straight-arm pulling strength that carries over to rows and pull-ups.
Skills and weights
Kufu is a hybrid app: the front lever tree sits beside your barbell and dumbbell work rather than replacing it. Skill work goes first in a session, while you're fresh. The Skills & Lifts plan runs two bodyweight skill days and two gym days a week.
