Weight training is a type of strength training, for developing the strength and size of skeletal muscles. It uses the weight force of gravity (in the form of weighted bars, dumbbells or weight stacks) to oppose the force generated by muscle through concentric or eccentric contraction. Weight training uses a variety of specialized equipment to target specific muscle groups and types of movement.
~BASICS~
To begin with, there are fourteen main muscles in a human body which we need to know for basic knowledge. Triceps, Biceps, Extensors/Flexors, deltoids, pectorals, trapezes, erectors, gluteals, lats, quadriceps, hamstrings, gastronemus, abdominals and abdominal obliques. Weight training helps us tone, build and metabolize these muscles by using various machines such as- lat pulls, tricep or bicep extensions, bench press, dumb bells, etc.
~PRINCIPLES~
The basic principles of weight training are essentially identical to those of strength training, and involve a manipulation of the number of repetitions (reps), sets, tempo, exercise types, and weight moved to cause desired increases in strength, endurance, and size. The specific combinations of reps, sets, exercises, and weights depends on the aims of the individual performing the exercise. Sets with fewer reps can be performed with heavier weights, as well as sets with higher reps with lighter weights.
In addition to the basic principles of strength training, a further consideration added by weight training is the equipment used. Types of equipment include barbells, dumbbells, pulleys and stacks in the form of weight machines, and the body's own weight in the case of chin-ups and push-ups. Different types of weights will give different types of resistance, and often the same absolute weight can have different relative weights depending on the type of equipment used. For example, lifting 10 kilograms using a dumbbell
