The most common reason for this is that you’re eating a little bit too much food. Because this program doesn’t incorporate a lot of high intensity cardio, it might mean that your workouts are using a little bit less energy than they normally would, and you have to adjust how much you’re eating accordingly. This is particularly true if you notice that you’re losing shape around your waist.

Don’t eat too little though - one of the aims of this program is to build some muscles in your glutes, which will help you to get that hourglass look. For this, you want to make sure that you’re not eating too little (which is why you may not lose weight on the program).
