How Much Exercise
You Really Need
Even Brief Bouts Of Activity Offer Benefits
For instance, if you can’t fit in one 30-minute walk, try three 10-minute walks. What’s most important is getting your heart rate up, and making physical activity a regular part of your lifestyle.
As a general goal, aim for at least 30 minutes of physical activity a day. If you want to lose weight or meet specific fitness goals, you may need to exercise more. Want to aim even higher? You can achieve more health benefits, including increased weight loss, if you ramp up your exercise to 300 minutes a week.
