Terms of service

8th Day Hybrid Training is training software operated by 8th Day Gym. It builds you a weekly programme for HYROX from your profile, your benchmarks and your race calendar, and it adjusts as you log results.

Access is currently by invitation. Accounts are created for athletes the gym has invited, and no payment is taken.

This is the part worth reading properly. The programming is written by software from numbers you supply, under a coaching framework set by the gym. It is not medical advice and it cannot see you.

• Get medical clearance before starting if you have any reason to think you need it.
• Tell us about injuries and limitations in your profile, and keep that current. The engine is told to avoid movements you have flagged, and it can only avoid what it knows about.
• Stop if something hurts. A session in the app is a plan, not an instruction, and skipping or scaling one is a normal part of training.
• You accept the physical risks of training, and responsibility for what you choose to do in a session.

• Sign in with Google, and keep that Google account secure. Anyone who can sign in as you can see your training data.
• One account per athlete. The programming is built from one person's numbers, so sharing an account produces programming that fits nobody.
• Give us accurate data. Benchmarks you guess at produce a week built on a guess, which is why the app lets you mark a figure as an estimate.

We will keep your programming coming, keep your data private as described in the privacy page, and fix things when they break. Generation runs against two AI vendors so that one having an outage does not stop your week.

We do not promise a specific result, time or ranking. Training outcomes depend on what you do, how you recover, and a great deal we cannot see. We also do not promise the service is never unavailable, though we watch it and are told automatically when something fails.

The data you enter stays yours. You give us permission to use it to run the service for you, which means storing it, showing it to the gym's coaching staff, and sending the relevant parts to the AI vendor that writes your week. We do not sell it and we do not use it to advertise to you.

You can stop whenever you like. Ask us and we will delete your account and the data attached to it. We can close an account that is being used in a way that harms other athletes or the service, and we would tell you why.

These terms change when the product changes. The date at the top says when, and anything material gets told to you rather than quietly edited in.
