Mark in Your iCal 

Take it from an old consejo: “Fail to plan, plan to fail.” Before you get going, sit down and figure out how exercise realistically fits in your schedule. Not a morning person? Don’t sign up for Zumba at 8 a.m.! Sounds simple, but too often we subconsciously sabotage ourselves. “Resolve to dedicate 20 minutes a day to moving your body in the space you have,” says Ary Nunez, a Nike celeb personality and trainer who works with Rihanna, Kat DeLuna and Alicia Keys using a mix of martial arts, dancing and calisthenics. “It can be as simple as performing pull-ups, push-ups and planks in your living room, or going for a walk with a friend.”
