No gym? No problem. This is a dumbbell-only workout that will develop strength and improve definition across your upper body and core muscles. It's also going to contribute to building a better posture and the even better news is that this routine only takes 15 minutes to complete.
Britany Williams is the trainer behind this workout which involves dumbbell exercises that target your shoulders, dumbbells and triceps — it will also engage the core while you're at it.
