A form of strength training, resistance training uses elastic or hydraulic tension to force muscular contraction, thereby building muscle. Instead of something like weightlifting, where an item is simply lifted to flex and contract the muscles, resistance involves items like bands or exercise machines to push, squeeze or bend in order to build up strength in skeletal muscles. There are benefits as well as risks that you should take into consideration when deciding if resistance training is right for you.
The benefits of resistance training are a combination of the benefits of many other forms of exercise. Training increases healthful habits that lead to a healthier body with more strength and endurance. The healthier the body, the better its rate of metabolism. Resistance training builds stronger skeletal muscles, which are especially beneficial as people age; it can prevent injury due to age and conditions such as osteoporosis. Aside from improving bone density and muscular strength, resistance training can also be a great cardio workout, improving the cardiovascular system and blood flow.
Resistance training also has chemical benefits. It increases levels of chemicals in the brain, such as serotonin, norepinephrine and dopamine. These chemicals can make a person feel better, which helps prevent feelings of depression.
While there are benefits, there are also risks to resistance training. If not done properly, resistance training can inadvertently cause injury and even permanent damage through injuries, from pulling or straining a muscle to something more serious like tearing a ligament. Therefore, it is crucial to take into consideration the comfort level of the activity, to be aware of your level of fitness and your limitations, and to research your resistance training options before beginning a program. Talking to a professional trainer and taking a resistance training class are two excellent ways to become more knowledgeable about and comfortable with resistance training.
