What is Strength training?

There are many different methods of strength training, the most common being the [[weight]]/[[gravity]] training and the training with the help of resistive equipment. When properly performed, strength training can provide significant functional benefits and improvement in overall health and well-being, including increased [[bone]], muscle, [[tendon]] and [[ligament]] strength, improved [[joint]] function, reduced potential for injury, increased bone density, a temporary increase in [[metabolism]], improved cardiac function. Training commonly uses the technique of progressively increasing the force output of the muscle through incremental increases of weight, elastic tension or other resistance, and uses a variety of exercises and types of training equipment to target specific muscle groups. Strength training is primarily an anaerobic activity. Strength training differs from ''bodybuilding'', ''weightlifting'', ''powerlifting'', and ''strongman'', which are sports rather than forms of exercise, although training for them totally depends on strength training. Many other sports use strength training as a part of their training regimen, notably [[football]], [[lacrosse]], [[basketball]], [[hockey]] and [[track and field]]. ==Some samples== Some samples of strength training exercises in a [[gym]] are shown in the picture gallery below. <gallery> | File:WPS.gif </gallery> == Basic principles == The basic principles of strength training involve a number of repetitions (reps), sets, tempo, exercises and force to cause wanted changes in strength, endurance, size or shape by overloading of a group of muscles.
