You can purchase BUILD YOUR BASE AT HOME from here and BUILD YOUR BASE AT THE GYM from here. Before you can buy the guides you will be asked to create an AFLETE account. You'll need this in order to access the guide, which is only available on the AFLETE app. Once you download AFLETE on your phone and sign in to the account you created (using the same email address), your guide will already be on there for you, ready to go!
