All of them! We specifically chose to use 3 handle widths, close grip, normal and wide. For most people starting with the middle (normal) grip will give you the best balance of the features and will be close to your standard grip on a bar. When you want to give your triceps some more work bring in your grip to close and you will feel the difference. Then if you are looking for the largest ROM and a good stretch in the pecs go all what way wide. By using all three widths you will get superior results regardless of your goals. Don’t forget to try all fo your arm, overhead, pushup and rowing motions with the different handles as well.
