We Understand

Whether you are an Owner or Manager of a Fitness Club or Boutique Studio, you’re busy managing your abundance! We don’t want you to worry about the substitution process, and you don’t have to. Sub Guru Streamline, Integrate, and Automate your instructor substitution process with our user-friendly software. A simple, easy, and efficient management tool fit for every studio.

The Gist

Elevate your substitution game with our app-based management software! Tailored for both Instructors and Studio management teams, it streamlines and enhances the process, ensuring efficiency and a hassle-free experience.

How it Works

Instructors and Management Teams access Sub Guru, locate their class, and choose “Request A Sub.” Our system then sends a push notification to the designated instructor group. Substitutes can accept or decline requests through the app. Sub Guru seamlessly integrates with the MindBody Platform, ensuring automatic updates for instructor changes.

Why it Works

Sub Guru’s effectiveness stems from its alignment with your business workflow. Management teams can customize Sub Guru by creating a personalized Instructor Tier list for each class type. This consolidation of information and scheduling changes in a unified platform minimizes errors and guarantees the smooth management of instructor-related tasks.


Tier System

Sub Guru enables you to choose a substitute instructor by considering factors such as class style, availability, and experience level. With the use of pools, you can pre-select your preferred candidates and efficiently send out substitution requests in a streamlined and systematic order, enhancing the overall organization and effectiveness of the process.

Mindbody Integration

Sub Guru ensures real-time updates for all schedule changes through seamless integration with MindBody. This guarantees that your team and clients can promptly view any modifications to the schedule as they occur, fostering transparency and keeping everyone in the loop.

Data Protection

Rest easy knowing that Sub Guru prioritizes data protection. Your information is kept safe, and secure, and is never shared, providing you with the peace of mind to operate without concerns about the privacy and security of your data..

Messaging Platform

Make the most of our messaging platform by leveraging Sub Guru’s group and private chat features. The app is designed to facilitate seamless communication, enabling the efficient management of substitution requests and approvals directly within the platform. This integrated approach guarantees a smooth and organized process for everyone involved.


For those with multiple studios, Sub Guru’s cross-location feature enhances the experience. Instructors can effortlessly be requested to substitute a class across various locations, introducing flexibility and convenience to the substitution process.

Enhanced Communication

Elevate your communication with Sub Guru’s enhanced features. Utilize our push notification feature to keep your team promptly informed of any schedule changes. This ensures that everyone stays up-to-date in real-time, contributing to a more efficient and synchronized workflow for your team.

What People are Saying

“There is a lot of guilt having to post on Facebook or send individual texts. Sub Guru eliminated that for me and I feel much better about my job.”


Yoga Instructor

“My favorite feature is the tier option! With this function, I know that the next best instructor is always notified without me stepping in! Sub Guru has also saved me so much time during the week. I no longer need to keep track of text, emails or even face to face conversation about subs! If you are an owner, you need to add Sub Guru to your business tools ASAP!”


Cycle Studio Owner

“My biggest problem BEFORE Sub Guru was communication. Filtering through multiple texts or often teachers not communicating changes to me. Sometimes the teacher would not change the class correctly in Mindbody and students would show to a class without a teacher. The second biggest issue was certain teachers were offered the bulk of classes while other qualified teachers were overlooked. This lead to feelings of favoritism within our organization. Sub Guru manages communication clearly and provides equal opportunities for all qualified teachers to sub. The value of my time has greatly increased and Sub Guru has made my life as a manager easier by streamlining communication while structuring the organization of subbing. I don’t have time to send multiple texts/make multiple calls to find a sub and group texts/emails are often ignored. My time is money. Sub Guru had saved me substantially in both areas. I am so grateful to have Sub Guru, the AMAZING owners who are such a blessing to work with, and a beautiful/seamless product that has saved me daily.”


Yoga Studio Manager

“If you own a yoga studio like me then you understand how frustrating it can be when a teacher cancels on a class with very short notice . This app has been a lifesaver for that. I absolutely love how this company has fixed an issue that has been going on forever. Thank you for allowing my business to run smoother!”


Yoga Studio Owner

“Where do start?! As an instructor in Los Angeles, I’ve had my fair share of issues finding subs for my classes. Some studios have you find your own, while others are left up to management. Using Sub Guru has not only saved me time, but it has taken so much STRESS of my shoulders! I am a PT instructor who also works a 9-5 and my schedule is forever changing! Oh and if you are an instructor reading this, you only get notified for the classes your actually teach! Amazing!”


Yoga Instructor

“We are returning to MindBody and you have no idea how much I have missed Sub Guru! Our staff and ME are so excited to have SubGuru back!”
