While on the hunt to discover with new, chic styling ideas for one of the most long-standing accessories on the market–the bracelet–we came across a photo of Rihanna working an upper arm cuff (above) and learned an important lesson: It’s not just about the kind of bracelet you wear, but the where you wear it matters too. But before you get to shopping the stylish styles pictured below, read on for exclusive tips on how to tone your upper arms straight from Adriana Lima’s trainer, Michael Olajide, Jr.

1. Stand with you feet shoulder width apart and grab a one pound hand weight for each hand.

2. Alternating hands, punch straight out, keeping your hands above your collar bone on the way out and back, getting to about 95 percent extension. Start slowly and pick up speed for 60 seconds, then rest for 30 seconds.

3. Next, frame your face with your fists and punch straight up to the ceiling, alternating hands, and repeat for 60 seconds, then rest for 30 seconds.

4. Finally, put both hands up, and punch your left hand straight out and back as fast as you can for 60 seconds for each arm. As fast as the punches go out they have to be pulled back.

Now that you know the workout—and one that can be done in the comfort of your own home, no less—click to shop our favorite upper arm cuffs.
