YAYOG Video Pack is a free expansion pack for the You Are Your Own Gym Android app, developed by Leafcutter Studios. It adds over 240 videos of YAYOG exercises being performed by Mark Lauren, enabling users to see the proper form and technique for each exercise. The videos are high-quality and provide a useful visual aid to accompany the written instructions in the YAYOG app.

It's important to note that YAYOG Video Pack is not a standalone app and requires the You Are Your Own Gym app to be installed on your device. The videos are organized by exercise type and difficulty level, making it easy for users to find the videos they need to supplement their workout routine. With this expansion pack, users can take their workout to the next level and get the most out of their YAYOG experience.
