Intensity and duration of exercise are mutually exclusive. It’s hard to stay active at the highest intensity for a long period of time. Many times, exercise is either at a higher intensity for a shorter period of time, or at a lower intensity for a longer period of time.

A advantage of walking at a faster pace is that it helps improve cardiovascular function andlevel of fitness. In time, a individuals who trains at higher levels of intensity can slowly increase his or her exercise time, building up endurance.

A advantage of walking at a slower pace is that it allows a individuals to stroll for a longer duration before becoming tired, which helps to build up endurance.

In time, a individuals can slowly increase the intensity (speed up his or her walking), improving his or her fitness level. Improvements in fitness occur by increasing the body’s use of oxygen (a.k.a., oxygen consumption).

Whether the intensity is high and duration is short, or the intensity is low and duration is long, relatively the same amount of oxygen is utilized and the same number of calories is expended.

One mode of exercise is no better than another – for intensity or duration. What really counts is to be consistent in any activity you choose to do.

Mixing it up – some days going for intensity – shorter, faster walks; some days going for endurance – longer, slower walks – can keep you on your toes (pun intended).

It can also make your exercise routine more intriguing, fit into any schedule, and keep you and your buddy satisfied and happy.
