Aerobic Fitness Accelerated

(HealthDayNews) -- If you want to improve your cardiovascular health but are nervous about overdoing it, the American College of Sports Medicine offers these guidelines:

• Exercise three to five days a week.

• Warm up for five to 10 minutes.

• Maintain your exercise intensity for 30 to 45 minutes.

• Gradually decrease the intensity of your workout, then stretch to cool down during the last five to 10 minutes.

If weight loss is your main goal, exercise for at least 30 minutes, five days a week.
