Hello all! A few people have reported issues with the sound on the videos. When loaded to Vimeo and watched from the computers of the instructors, the sound is completely normal. I'm really sorry if anyone is having troubles with the sound! We have contacted Vimeo about it, and they have said the most common reason for this is if your device is older/internet program (eg Safari on Mac) is not up to date - you could try updating your running system.
New videos loaded yesterday, and more to come later this week!
