You exercise consistently
Even if you're not hitting it hard every day, getting enough exercise each week does make a difference. If you're getting at least 150 minutes per week of exercise and two days of strength training in, you're probably on your way to being fit. The American Heart Association recommends that adults get 30 minutes of moderate-intensity aerobic activity at least five days per week (150 minutes total) or you can kick it up a notch and do a higher-intensity workout for at least 25 minutes three times per week (75 minutes).
