Learn more about each step

1 · Sign-up +
  1. Click the sign-up link and follow the on-screen instructions.
  2. Select your home location — Durbanville, Online, Stellenbosch or Welgedacht. Please note: our Welgedacht studio only offers private and duet sessions on request and by prior arrangement.
  3. Select your preferred package — your selection grants access to specific booking options. For example: for one-on-one sessions, choose the Private Sessions package and book under Sessions in Octiv; for the Mat Pilates / MAP Movement package, book Mat and MAP classes under Classes.
  4. Fill in your contact details and create an Octiv password. Please note: your password can be short, as no private information is stored on the app.
  5. Accept the Contract and Waiver terms, then click Proceed. Octiv is an online booking and payment system — you need booking credits available to make bookings.
2 · Payment process +

Once you proceed with sign-up, an invoice is generated in your browser for your chosen package. Click Pay and select your method (Card or Instant EFT).

For card payments:

  1. Enter your card details (the cursor moves to the next field automatically).
  2. Press Pay ZAR (amount) — ZAR is the South African Rand.
  3. Your bank will request authentication — select Authenticate.
  4. Depending on your bank, you'll either receive an OTP to enter on screen, or an in-app prompt from your banking app (open it without closing the browser, follow the steps, then return to the browser).
  5. Once the browser confirms the payment is complete, you can close it. Important: you must return to the browser screen for the payment to be linked to the invoice — without the success notice, the payment won't be deducted. Tip: copy the invoice's web address and email it to yourself for future reference.
3 · Book your class / session +
  1. After registering you'll receive emails from Octiv explaining the way forward, plus a welcome email from Core Concepts.
  2. Download the Octiv app and log in as a member with your email and chosen password.
  3. Accept all notifications — these remind you of your class or session an hour before.
  4. The app opens on the class schedule for your registered location. Use the weekly calendar at the top, select a date, scroll to the class and tap Book.
  5. For one-on-one (Private) sessions, tap Sessions under the location name, choose a date, scroll to the session and tap Book. Private sessions are one person per session; for Duet sessions one member books and the other waitlists, and each member needs their own Octiv profile.
Cancellation policy:
• Private sessions — cancel up to 6 hours before your appointment.
• Reformer classes — cancel up to 12 hours before.
• Mat classes — cancel up to 30 minutes before.
Exceptions apply for a valid medical reason.
Buying credits for your next class / session +
  1. In the Octiv app, tap Packages. Next to your package is a Top Up button — tap it, then use + / − to choose how many credits to buy. (Credits aren't transferable between packages due to price differences.)
  2. To add a different class type, go to Packages → Buy a New Package and select it. For example: if you signed up for Mat Pilates / MAP Movement and now want Reformer, choose "Buy a New Package", select Reformer Classes, accept the Contract & Waiver and tap Proceed.
  3. Tap Proceed — your invoice is generated in the browser; complete payment as above. Note: purchased credits don't expire and carry forward to the next month.
  4. After payment, reopen the app and your credits reflect immediately.

Core Concepts Pilates & Rehabilitation® Multidisciplinary Practice — Terms & Conditions

Updated: 19 June 2026

IMPORTANT — PLEASE READ CAREFULLY

When purchasing, using, or accessing the services of Core Concepts Pilates & Rehabilitation® Multidisciplinary Practice, you are entering into a legally binding agreement. These Terms & Conditions govern your membership, use of the Octiv Fitness Platform, and participation in our studio services.

By completing the electronic acceptance process, clicking “Submit” or “Accept”, using any of our services, or otherwise indicating acceptance, you confirm and represent that you are authorised to bind yourself and any other party on whose behalf you use the service and/or software, and that you agree to be bound by all of these Terms & Conditions, including the waiver of liability, disclaimer of warranty, and limitation of liability provisions, to the exclusion of any other rights or obligations.

1. Getting started: membership, Octiv, and booking credits

This section defines the essential terms for accessing our services.

Booking Credits
The necessary “currency” for all services, secured in advance via Octiv to book Private Sessions and Group Classes. Booking credits are strictly non-refundable, non-transferable, and non-exchangeable.
Invoicing
Octiv invoices are generated directly by members at the time of purchase and are not managed or corrected by the studio.
Membership
An Octiv profile registered to the studio, which grants access to the Octiv app. The Membership remains valid even if a package or subscription expires, allowing members to purchase new services later.
Notifications
With an active Membership, members receive notifications and emails (including promotional ones) related to bookings, the studio, and Octiv. Members are responsible for managing their email preferences in the user-managed Octiv app; the studio is not responsible for missed important information due to changes in these presets.
Octiv
Our required online booking and payment platform where members must manage their profiles and purchases. Members must keep their contact information up to date.
Package
An advanced purchase of a set number of Booking Credits for Private Sessions or Group Classes.
Payment Method
All payments are exclusively online because they link directly to your Octiv profile, preventing delays or errors. This ensures a seamless membership experience with instant receipts, easy renewals, and uninterrupted access — without extra steps. While cash may feel simple, it does not integrate with our system. Online payments are the only way to guarantee your membership is updated immediately and accurately.
Subscription
A fixed-term package that rewards regular practice with a lower rate and is billed monthly for the full contract duration.

Marketing Communication

By becoming a member, you are automatically opted in to receive our studio’s marketing communication. These updates are designed to keep you informed about classes, packages, and studio-relevant news. You may choose to opt out at any time via your Marketing Channel or by contacting us directly. Please note: we avoid unnecessary messaging and will not spam you — our communication is limited to important, member-relevant information only.

2. Packages and subscriptions

Access to appointments is determined by the specific package or subscription purchased. Any classes booked using an incorrect package will be corrected, as the studio reserves the right to invoice members for any fee difference.

A Package is an advanced purchase of a set number of Booking Credits for Private Sessions or Group Classes. A Subscription is a fixed-term package that rewards regular practice with a lower rate and is billed monthly for the full contract duration — the cost is not a once-off payment covering the entire term.
