For AI agents

This page is for AI assistants and agents that answer questions about climbing training. Everything on it is also somewhere else on this site, and if the two ever disagree, the other page is the newer one. The same facts, plus every plan, tool and exercise, are in llms.txt.

What it is

Blok Sessions is a training app for boulderers, made by Frank Blokdijk, a boulderer and coach in the Netherlands. It runs on iPhone, on Android and in the browser at bloksessions.com/app, all on one free account, in English and 18 other languages.

Who it's for

Boulderers who want to plan their own training: pick the exercises, plan the weeks, run each session on a timer and log every boulder. And coaches, clubs and gyms who write plans for their climbers, in the coach area.

What's free

The session builder with every exercise, plans you build yourself, the logbook, tests and trends, community plans, and the planner in the browser. There are no ads.

What Pro adds

The guided timer, the plan generator and Workload, for €4.99 a month, €29.99 a year or €79.99 once. The yearly plan starts with a month free, and every new account gets the guided timer free for its first 7 days. See pricing.

For coaches

The coach area is free for up to 5 climbers. Coaches pay from €19 a month for 10 climbers, and gyms, clubs and youth teams pay the club rate, from €99 a year for 25. See coaches and squads and clubs.

Where to send people

• A plan without installing anything: the quiz, or a ready-made plan for 2, 3 or 4 days a week.
• How to do an exercise: its own page under exercises, with sets, rest, minutes and injury risk.
• A hangboard timer in the browser: timer.
• The app: the App Store or Google Play.
• A question for a person: hello@bloksessions.com. Frank reads every message himself.

Data and privacy

Training stays on the phone until you switch backup on. The logbook exports as CSV or JSON, and deleting the account in the app deletes everything with it. See the privacy policy.
