Peloton shares dropped more than 4.5% in premarket trading Thursday on a report that Apple is working on a subscription service for digital fitness classes. .

Apple plans to offer virtual workouts via an app for the iPhone, iPad and Apple TV, Bloomberg reported Thursday. Apple's move is part of a broader effort to launch new subscription plans that bundle several of its services, including Apple News+, Apple Arcade, Apple Music and others, Bloomberg reported.

Apple declined to comment on the Bloomberg report. .

Developers have complained that Apple emulates their software and then introduces it as new features in iPhones and other products.
