Project LGN: Heavy weights vs. light weights

Working with lighter weights actually stimulates your muscles 25 percent more than heavy weights.  You build muscles by pushing to the point of fatigue, not by straining with heavier weights.  The best thing to tone your muscles is to choose a weight that you can lift for about a minute before you become too tired to continue. If it takes you much longer than that to reach fatigue, the weight is probably to too light and should go up a bit.

Remember to alternate your arms and legs each day so you don't do the same muscles two days in a row (except for abs and calves, you can do them everyday). And vary your exercises cause muscles have memory.
