Starting out on a new exercise routine can be exciting, but it’s important to use caution to avoid injury. If you get hurt it can put a serious damper on your fitness efforts. First, don’t skip your warm up. Your body isn’t designed to go from resting to exercising intensely, so perform a few gentle exercises to warm up your muscles. You should also slowly build up to intense levels of exercise if you you’re just starting out. Along the same lines, don’t rush your exercises, especially those with weights. Be sure to keep a water bottle with you so you don’t get dehydrated.
