Why jumping rope may improve your job performance

In a recent study at Texas Tech University, people scored nearly 9 percent higher on a word and color-matching test (used to measure attention) following a 30 minute high-intensity workout. What's more, levels of a protein that's critical for nervous-system health increased post-exercise as well. Boost your smarts by doing at least 30 minutes of heart-pumping cardio like jumping rope, every day.
