What Is Strength Training?

Traditional strength training consists of performing one to three (or more) sets of exercises on a specific, isolated muscle group. One rep, or repetition, equals one complete movement of the exercise from start to finish. For example, for a bicep curl you might begin with your arm extended down by your side holding the weight, say a dumbbell, curl the weight upward to your shoulder by bending your elbow, and then lower the weight back to the starting position. That's one rep. Do that 8-12 times and you've completed one set of bicep curls. Rest for 30 to 60 seconds to allow your muscle to recuperate and you're ready for the next set.
