Crazy commute? No problem. Mile-long to-do list? Bring it on. Mini work crisis? Easy.

Just make dumbbell your middle name and you'll be practically immune to these kinds of things. Why? Because people with decent muscle mass have an easier time recovering from mental stress.

Pump Up the Jam
Whether you use dumbbells, resistance bands, or your own body weight to build muscle (think push-ups), you're one step ahead of the stress game. Having a lean body mass (more muscle, less fat) helps your body normalize blood pressure more quickly after a mentally stressful event, because a fit body does a better job of ridding itself of sodium. And that takes a big load off of your heart and arteries when you're under the gun. Test your sodium smarts with this quick quiz.
