The Lowdown

SubGuru is app-based management software that makes the substitution process easier and more efficient for both Instructors and Studio Managers.

How it Works

Instructors or Studio Managers log into SubGuru, find their class, and select “Request A Sub”. Our system will send a push notification to the designated instructor group assigned. Subs are able to accept or deny a request via the SubGuru app. SubGuru currently links seamlessly with the MindBody Platform and instructor changes are made automatically.

Why it Works

SubGuru fits your business’ workflow. Studio Managers have the option to set a customized Instructor Tier list for each type of class. SubGuru prevents errors by keeping all information and Instructor scheduling changes on one single platform.


Tier System

Select a substitute instructor based on class style, availability and experience level. Pools allow you to select your preferred substitutes and send out the request in a streamlined, systematic order.  

Mindbody Integration

SubGuru seamlessly integrates with MindBody to allow for real-time updates. Owners, Managers, and Members can see all schedule changes as they’re made.

Data Protection

Operate with the peace of mind knowing that your data is safe, secure, and never shared.

Messaging Platform

Streamline and organize your communications. Substitution requests and approvals are done through the app, making the entire process hassle-free.


Have more than one studio? Even better! Instructors can be requested to substitute a class across multiple locations.

Enhanced Communication

Keep your Team and Members up-to-date with any schedule changes using our push notification feature.

Her vision is to build conscious awareness and integrity within the fitness industry and SubGuru is the management solution to do just that!

Andra Rasby, M.B.A.


Andra Rasby understands the sports and fitness industry from the inside out. She holds an MBA with a concentration in Sports Business, is a former Division 1 Athlete, and a certified Yoga Instructor. As both a Client and Instructor, Andra is well familiar with Group Fitness and the operations behind the Instructor Substitution process. She recognized a disconnect in finding the most appropriate substitutes for group classes. There were too many steps, lost emails, and last minute requests. With a desire to fix this problem, she teamed up with Sarah to design SubGuru and says, “I want Owners, Managers, and Instructors to spend less time worrying about finding the right Teacher and more on the quality of the class.”

Social Impact

Sub Guru believes that strong communities have the power to make an incredible impact. We are committed to giving back to our collective communities. With every dollar earned, we invest back into the community of Lincoln, Nebraska, where SubGuru was founded.
