    During anaerobic exercise (exercise that does not require oxygen to produce the necessary energy, ATP, to carry out the activity, such as weight lifting), lactic acid (lactate) is formed when pyruvate (an intermediate substance in glucose metabolism) combines with hydrogen, in the presence of an enzyme, lactate dehydrogenase. Once lactic acid is formed, it quickly diffuses from the muscle into the blood, where it is buffered and carried away. If this didn't occur, you'd tire out very, very quickly. Eventually, though, as you continue to work out, the clearance of lactic acid can't keep up with its formation, and eventually builds up in the muscle and blood, causing fatigue. The acid build-up inactivates certain enzymes that are involved in energy transfer. It also decreases the muscles' ability to contract. These processes lead to fatigue. The lactic acid that has remained in the muscle can be reversed back into an energy source (pyruvate) during recovery or when the pace of exercise is slowed. How quickly this recovery can occur will vary from individual to individual. This process doesn't create more energy than you began with. Some of the lactate has dissipated from the muscle. Although some of the dissipated lactate may be converted into glucose during the Cori Cycle. Hope this info helps.

    All he's saying is that when you lift weight, you should allow your muscle to res after a period of heavy lifting.. When the muscle is tired out(full of lactic acid) less contractio occur= it becomes weak.

    As far as swift comments, I said that because it depands on each individual's activities during the day. Some people just sit in the office all day while some requires great energy to do their job so take it this way. look at ur level of activity and u decide how much u shld each.

    Remember there's no guarantee that each work out method is gonna give u the results you want. Some work for you and some don't.The best thing is to try it out and see which is best work out for you. It's the same thing like acne medicine. SOme people say that this type A med works wonder while other who use it has no effect at all....

    P.S Pharmteg, Don't get me started on Action potential that topic is killing me.
