This is the gradual and continual addition of weight to the exercise over time, as the previous weights become too easy to lift, so that your muscles are continually forced to work harder and thus increase muscle strength, size and tone. After two or three weeks you may find that pressing 20 pounds has become too easy, and that you can do more than your chosen number of repetitions with little or no difficulty. The progression principle demands that as soon as the weight you are using is no longer a challenge, you must raise it. You progressively increase the weight you use for a lift so that you continue to make gains in muscle tone, size, and strength. Please understand that an increase in repetitions is an increase in strength.
Many people think strength gains are only obtained when they increase the weight.
But if you have increased the number of repetitions you can do with good form, you have increased your strength and more than likely, your muscle size and tone as well. Please check back for Part five, where I'll discuss exactly how to avoid the common mistake of over training. Until then, be sure to use the right amount of weight and number of repetitions for each set you do so you can achieve the results you desire. Good luck, and enjoy all the wonderful benefits of strength training. Robert Clodfelter Copyright 1999 Hardgainer's Home Gym Home Page .
