Some safty stuff that is very usefull if you dont want to harm your self while excersizeing.
Major causes of injury when strength training are improper lifting techniques combined with lifting weights that are too heavy. Each person must understand how to do each lift correctly before starting his/her strength training program. One should always do weight training with a partner or spotter, who can observe performance while exercising. To ensure safety and the best results, both should know how to use the equipment and the proper spotting technique for each exercise. A natural tendency in strength training is to see how much weight one can lift. Lifting too much weight forces compromise in form and may lead to injury. All weights should be selected so that proper form can be maintained for the appropriate number of repetitions. Correct breathing is another safety factor in strength training. Breathing should be constant during exercise. Never hold your breath, as this can cause dizziness and even loss of consciousness. As a general rule, one should exhale during the positive (concentric) phase of contraction as the weight or weight stack moves away from the floor, and inhale during the negative (eccentric) phase as the weight returns toward the floor.
