Unfortunately, for the majority of people, a variety of dumbbells will be required. In order to promote muscle growth, you need to choose a weight that's challenging you - causing you to reach muscle failure within a given rep range.
Example: For rotator cuff exercises and other shoulder exercises, a lighter weight will probably be needed. For back and chest exercises, heavier dumbbells will be required, and for leg work, even heavier dumbbells on top of that. So a good variety of dumbbells is recommended to get the most out of your ATHLEAN-X Training.
