I want to switch to a different program within the app
You can reset your plan by going to ME < PROGRAM in the App. This page will give you the option to change, reset, restart, or begin a new transformation. If you begin a new transformation, it will ask for your height and beginning weight stats again, but it will also allow you to choose a different program and change your goals. If you restart your program, your past program will disappear and become a clean slate for you to start over. Both are great options, but if you want to keep in your history the record of what you've already done, be sure to choose BEGIN NEW TRANSFORMATION instead.
