Most people equate exercise with words like “chore,” “boring” and “necessary evil.” But sometimes—in yoga class, on a nature walk or during a dance lesson—it’s as if the stars align and those negative perceptions melt away. Rather than dreading working out, you begin to associate sweat with a sense of purpose, something that drives you towards your goals and makes you feel invincible.“Athletes call this ‘getting in the zone,’ which is really just their version of psychological flow,” explains Harvard psychologist Jeffrey Brown, author of The Competitive Edge: How to Win Every Time You Compete.Brown says that just about any kind of exercise can put you into a flow state as long as it meets three criteria: First, your fitness activity needs to have a clear objective.

With cardio-type workouts, the rhythm of your breathing, the sound of your footfalls and other physical feedback can help you stay focused on the subtleties of your workout and achieve a state of flow.Activities best suited to your personality are the likeliest to induce flow, notes Brown.
