Programs are viewed entirely on this website (no files are sent to you personally) and never expire. You will always be able to log in and access your workouts.
After you have signed up and purchased your program, you will take these 3 steps.
Step 1. Log in using the email and password previously used to sign up.
Step 2. Once logged in, click on the menu at the top of the screen where it says programs.
Step 3. Once on the programs page, you will click on the picture with the title of the program you've purchased. After that you will be redirected to the main page of your program. (This is the last step)
I hope these instructions help :)
