Swap out your old, baggy t-shirts for tops that fit to your body. Not only will this allow you to focus on the workout instead of your shirt getting in the way of your dumbbell row, but being able to see your muscles in action can be the motivation you need to push through a tough set.
If you don't feel comfortable in tight clothes, you can:
? Opt for darker colors, which are often more slimming than lighter hues.
? Wear well-fitting t-shirts, rather than tank tops.
? Wear capris or full-length leggings, rather than shorts.
