If your exercise routine doesn't include weight training, I have news for you: It should.
The American College of Sports Medicine recommends that all healthy adults weight train at least two days a week (and this is in addition to at least three to five days of cardio exercise)! A common fear with weight training, however, is injury. How can you avoid it? What constitutes right from wrong in the weight room is heavily debated in the fitness injury. There are endless weight machines—with new variations coming out every year—so this further adds to the confusion.
However, understanding basic human biomechanics, particularly for the low back, shoulder, and knees, or the top three areas most prone to injury, is the first step in learning how to navigate the weight room safely.
