METs
One MET is the amount of energy your body uses when you're
resting. If a physical activity has an equivalent of six METs, its
energy demands are six times that of your resting state. The MET
is a useful measurement because it accounts for differences in
body weight.
Time: How Long You Exercise
Sustained exercise conditions your heart, lungs, and muscles. The
longer you are able to sustain exercise within your target heart
range, the greater the aerobic benefits.
To begin, maintain two to three minutes of steady, rhythmic
exercise and then check your heart rate.
The initial goal for aerobic training is 12 continuous minutes.
Increase your workout time approximately one or two minutes
per week until you are able to maintain 20-30 continuous minutes
at your training heart rate.
