Obsidian Strength

A programme written by a coach, and the app to run it.

Follow a written programme or build your own from the same library. Every set logged, every lift tracked, and a straight answer about whether you're getting stronger.

Find your plan
Four questions, about a minute. No payment until you've chosen.
What you get
A week that's already written, or one you write
Assign pre-written sessions to your own days, build your own from the exercise library, or have a coach write the lot and update it as you go.
54 exercises in the library
Written coaching cues, and 10 filmed so far, so you're never guessing what a name means.
Logging that works in a gym
Weight and reps, set by set. It keeps working when the signal drops and syncs when it comes back.
Progress, stated plainly
Heavier, more reps at the same weight, or no change. If nothing moved this week it says so rather than inventing encouragement.
What it costs
App
Pre-written sessions, full exercise library, all tracking. No coach.
£14.99 a month
£119 a year
Coached
A coach writes your programme, reviews your form on video and answers your messages. Three tiers, depending on whether you want check-in calls and how often.
From £79 a month

Billed on the day you start, then the same day each month or year. Cancel whenever you like from your account page and you keep access until the period you've paid for ends. No minimum term and no cancellation fee.

Straight answers
Can I write my own sessions?
Yes. Build your own from the exercise library, or use the sessions already written for you and change what you want. Most people start with a written one and edit from there.
What if I can only train some weeks?
Fill as many days as you want. Three sessions done is three sessions done. Book time off and those days are left out of your completion, so a short week doesn't read as a missed one.
Do I need a gym?
No. We ask where you train and only offer exercises you can actually do there.
