You need an internet connection to use the app.
This is due to the amount of content we have available to you. We regularly release and improve content too so you can always have the latest workouts and exercises.
However we are working towards enabling offline content, it's a big change that we're working hard to get done for customers with poor internet access in the gym.
In the meantime, while we're working on new features and improving the core parts of the app you can load in your workout while on an internet connection then leave the app open. demos videos won't stream but you can still follow the plan and get a good workout in!
