Warming up before Exercise

Today's Tip: 

 A PROPER WARM-UP

A warm-up should be part of every exercise program, as it prepares
your body for more intense activity. It should consist of 5-10 minutes
of low-intensity large-muscle group activity. A good warm-up is to
perform a lower-intensity version of whatever exercise you are about
to do. For example, if you are going to do fast walking, then the
warm-up should entail a slower-paced walk to acclimate your muscles.
