Disadvantages

Some drawbacks of aerobic exercise include:

• 
  Overuse injuries because of repetitive, high-impact exercise such as distance running
  
• 
  Is not an effective approach to building muscle
  
• 
  Not an effective form of fat loss, unless used consistently
  

Both the health benefits and the performance benefits, or "training effect", require that the duration and the frequency of exercise both exceed a certain minimum. Most authorities suggest at least twenty minutes performed at least three times per week.^[27]
