Stick to an exercise regimen. If you don’t want to pay for a gym membership, try strength-training at home. The muscle you develop will help increase your metabolism: the bodies of muscular people burn more calories even while they’re at rest.[19] To help you stick to your regimen, keep a workout journal. Plan out when and where you will work out each week and stick to it. Each time you work out, write down what you did and for how long.
To keep your heart in shape, do cardio. One particularly effective way to improve your cardiovascular health is to do interval training, which means alternating between low- and high-intensity activity. This has been shown to be a quick and extremely effective way to improve heart health and endurance.[20] (Anyone over the age of 60 or who has heart disease, high blood pressure, or arthritis should consult a doctor before attempting interval training.)
