Strength training is exactly what it sounds like it needs to achieve, making your body stronger. The results can burn fat, calories, and ultimately increase or decrease your weight positively. Strength training include exercises that are not as quick and fast as plyometrics. It can also help you with your joints, stability, health, and even your posture.
The basics of strength training is to break down your muscles and then you recover for a day or two so your muscles rebuild ultimately making you stronger. This is because when a muscle rebuilds, the cells increase and in size as well. What is taking place is called muscle hypertrophy.
Logically, you need to be lifting weights heavier than what your body is comfortable and used to. This does not mean to go super heavy because that will cause injury.
Strength training is typically two to three days a week that are spread out to recover and rest. Working out three to five exercises with three sets of five to fifteen for upper body and lower body each is essentially an ideal way of getting stronger.
