This Quick Triceps Workout Will Carve Super Strong Arms

Good news if you’re wondering how to lose arm fat: It doesn’t require taking any crazy pills or potions—or pumping major iron. (BTW, here’s the real difference between lifting heavy vs. light weights.) As the largest muscles in your arms, the triceps are responsible for the most upper-body definition and small, targeted movements can make a big difference. With this targeted triceps workout routine (demonstrated by NYC-based trainer Janeil Mason), you'll not only feel the burn and be well on your way to discovering how to lose arm fat, but you'll also strengthen your core too. Bonus: It also incorporates cardio intervals to help burn calories, which will help you lose weight and uncover those newly strengthened arm muscles.

How it works: Three days a week, do 3 sets of the prescribed number of reps for each exercise (including the cardio interval!). Focus on using proper form, and don't worry about completing the exercises at a quick pace.

• Pulse right arm one inch up and down, keeping arm as straight as possible.

Do 25 pulses, then switch sides.

• Place hands directly below shoulders, feet hip-width apart.
• Keeping elbows pointed back and as close to your sides as possible, slowly lower body to the ground.
• Once your chest touches the floor, press back up to a straight-arm plank. (Up Next: Triceps Dips Are the Upper-Body Move You Should Master ASAP)
