Weights

During the first couple of training sessions, you'll want to go pretty light just to get a feel for how to do the movement correctly. After you feel comfortable with the form, begin adding weight.

Even an experienced lifted should always do his first set as a warm-up with practically no weight to flush to target muscle and connective tissue with blood. On the second set, add a couple of small plates and do the exercise again. Was it still east? If so, and assuming you used good form, add more weight. If you struggled to reach 12 repetitions, add just a little bit of weight. (Adding weight on successive sets is called pyramid training and is one of the safest ways to train.)

Continue adding weight until it becomes tough to complete 8-12 reps. Your goal is to train in the range where you reach muscular failure at 8-12 reps. Once you find a challenging weight, stick with it. So you'll become stronger and be able to increase the number of reps. Once you can do 12, it's time to increase your training poundage by about 10%. At this heavier weight, you won't be able to do 12 reps, but with time you'll once again be able to. Keep working in this fashion.

The principle behind this type of training is known as overload. It states that for improvements to occur, you must impose a demand on your muscles greater than what they're accustomed to (for bodybuilding purposes, about two-thirds of your maximal strength). Your muscles compensate for this strain on the cellular level by adding protein to grow thicker and stronger. At that point, the same load is no longer sufficient to induce further changes, more load must be added. That is, you must progressively add training stimulus to make continued improvements.

Keep track of your training poundage by recording your weights, sets and reps in a training log alongside a list of your exercises.

Some bodybuilders swing and heave, cheating for the sake of pushing heavier weights. Remember, the name of the game here is not weightlifting, but rather bodybuilding.
