Exercise is good for your heart, your waistline, and even your mental health, but the Centers for Disease Control and Prevention (CDC) report that less than half of U.S. adults get the recommended amount of aerobic activity, and just 20 percent do the recommended amounts of strength training exercise.

It can be hard to fit regular exercise into your daily schedule, but with all of the benefits, making time for it should be a priority. According to the CDC, adults should get 150 minutes of aerobic activity each week and strength training on two or more days per week. The former could be as simple as taking a brisk walk every evening after dinner.

Finding the time and motivation to get your activity in is easier when you surround yourself with motivational people, like the Twitter influencers we’ve gathered together here.
