Consistent activity is critical for maintaining wellness: cardiovascular health included. It is also important to be aware of activity's limitations:

• It cannot undo the damage caused by eating foods that are harmful such as trans fats, and saturated fats.
• It cannot compensate for chronic excessive caloric intake. It takes only 3 minutes to ingest a 450 calorie slice of pizza. it takes over 50 minutes of high impact aerobics for a 160 lb man to burn 450 calories.

Remember: You cannot outtrain bad eating habits.
