If you do not have a weight goal listed in Step 1 of your start page, you have signed up for the Spark5 program, which is for weight maintenance only. With the Spark5 program, you are not able to create or edit a weight goal.
If you are in the Spark5 program but want to create a weight goal, you will need to reset your program
. Once you reset, you will need to choose the weight loss program and set up your goals, including your weight goal.
