Weights are exercise equipment used for strength training. The term is commonly used as a shortened form of the term free weights, but it can also refer to any exercise machine that uses weighted plates as the major opposing force.While there is debate over whether weight machines or free weights are better, machine weights are generally considered safer. On a machine you can lift more outright weight, working the main muscle (prime mover) harder, but with free weights you also work the smaller supporting synergist and stabilizer muscles, which aids balance and perhaps burns more calories. You can lift heavier outright weight with a machine because the tension is the same through the whole range of motion, while with free weights the weight is limited by "sticking points", so you are not putting the muscle through maximum load in other parts of the range of motion outside of the "sticking points". This is the main reason why machine weights were invented. It is general convention that machines are given to beginners, while free weights are given to more experienced people, so free weights can be considered a more advanced form of exercise.

Reduced to English troy-weight, the Hebrew weights were: (1.) The gerah (Lev. 27:25; Num. 3:47), a Hebrew word, meaning a grain or kernel, and hence a small weight. It was the twentieth part of a shekel, and equal to 12 grains. (2.) Bekah (Ex. 38:26), meaning "a half" i.e., "half a shekel," equal to 5 pennyweight. (3.) Shekel, "a weight," only in the Old Testament, and frequently in its original form (Gen. 23:15, 16; Ex. 21:32; 30:13, 15; 38:24-29, etc.). It was equal to 10 pennyweight. (4.) Ma'neh, "a part" or "portion" (Ezek. 45:12), equal to 60 shekels, i.e., to 2 lbs. 6 oz. (5.) Talent of silver (2 Kings 5:22), equal to 3,000 shekels, i.e., 125 lbs. (6.) Talent of gold (Ex. 25:39), double the preceding, i.e., 250 lbs.
