Get ready to say hello to strong, toned arms with this 20-minute workout that targets your triceps and chest. And while your goal may be to get rid of "armpit fat" completely, keep in mind that most people have at least some fat in that area, despite what you may see on Instagram.

But with the right exercises, along with cardio and a healthy diet, you can sculpt strong, sleek arms.

"Adding some muscle to the areas surrounding the armpits is the best thing we can do to tighten that area, along with a proper diet and lifestyle," Joey Thurman, certified personal trainer, tells LIVESTRONG.com. "Adding muscle can actually stretch out cellulite and make that area tighter and look better."

In addition to strengthening exercises, you'll also need to reduce your overall body fat reduction, since you can't "spot reduce" one area, Thurman says. One part of that is adding cardio. Thurman says to look for activities that also work your arms, including as boxing, jumping rope or rowing.

The other, arguably most important part, is a healthy diet. To lose weight and body fat, aim to cut 500 to 1,000 calories a day from your normal diet to lose one to two pounds a week in a healthy way, according to the Mayo Clinic.
