When stress isn't just stress, exercise can work wonders, too. There's a host of research proving that people with anxiety and depression can find major help in working out. According to the Anxiety and Depression Association of America, regular exercise has been found to help with various anxiety disorders, including panic disorder and OCD. Celebrities, including Lena Dunham, have talked about about how a regular exercise program has helped with her anxiety.
Toning your arm muscles will certainly get you the definition you seek, but adding some extra protein to your diet will get you there even faster.

When she's working out sans equipment, Marraccini's favorite exercises are all things core-related. "A strong core never goes out of style," says Marraccini. This makes sense, considering that having a strong and stable core is essential for both everyday movements as well as exercising. While regular crunches really only target the upper portion of your abdominals, runner's crunches work your entire core as you sit all the way up, including your obliques, lower back, hip flexor muscles, and rectus abdominis (which is what you probably think of when you think "six-pack" muscles).
Take a towel—technically not gear!—and run it underneath the seat of a chair—also technically not gear!—and, with the back of the chair facing away from you, do a set of biceps curls. This works only with standard, four-legged chairs in the 10-to-15 pound range, although if you can figure out how to manage it with your caster-mounted office chair, more power to you.)
The best part about exercising is how much you enjoy the downtime. If you think laying on your couch all day is enjoyable, it has nothing on that hour you spend as a couch potato after a rigorous workout. Jay-Z said it best, “in order to experience joy, you need pain.” The harder you push yourself while exercising, the better you’ll feel when you’re relaxing.
If you're ready to move on from classic Bulgarian split squats, Swan's amped-up variation gets your upper body in on the action for a true total-body exercise. "This combination move works your legs, butt, chest, back, arms, and core," she says. "And it not only hits all the major muscle groups—it also lets you work on balance." Give it a shot and you'll see why.
