People nowadays are more conscious about their health. Many people regularly go to the gym to keep fit and burn some excess flabs. These people chose to workout rather than purchase a weight-loss pill. Weight training and other cardiovascular exercises are done in the gym because people do not have the necessary equipment. Equipment like the thread mill, stationary bikes, and weight-lifting bench consume much space and may not fit in most people's houses. It is true that using weights and exercise equipment is the fastest way to gain muscle mass and strength. While there it is not harmful to lift weights, there are people who work for long hours and may not have the time to regularly go to the gym. They may not have the money to set up or buy gym equipment at home. There are also people who travel a lot and may encounter difficulties in finding a good gym. Plus, there are times when people can't even go to the gym on a regular basis because of work and family demands.



Athletes who train in martial arts, baseball, and other sports try hard not to get bulky. Additional muscle mass may affect the mobility and movements of these athletes. However they still need the type of strength, endurance, and muscle definition that can be developed through weight training exercises.

These athletes and other busy people may still tone and strengthen their muscles without the use of weights or other equipments. Anaerobic exercises like push-ups, pull-overs, and pull-backs are typically performed to develop power and tone the muscles. Some health studies claim that these anaerobic exercises should be done in repetitions of 100 for maximum development. Some studies claim that muscles that are trained under these conditions performed better in high intensity activities than those who lifted weights.

Plyometric training is another way of developing speed and power without the use of weights and other equipments. This kind of training seeks to improve the reaction of individuals through vigorous muscle contraction because fast extraordinary contractions.

Examples of lower body plyometric exercises are: standing jumps, tuck jumps, split jumps and long jumps. Upper body plyometric exercises may include press and hand claps. Another method for developing one's upper body may be done with the use of a medicine ball. A partner drops a medicine ball towards the chest of another person who catches the ball and throws it back This method is considered a high intensity exercise and should only be done after basic conditioning.

Dynamic tension is a self-resistance exercise training which includes pitting one's muscles against each other. According to research, works by tensing the muscles of particular body parts and later moves the body part against the tension as if a heavy was being lifted. These kinds of exercises builds strength, endurance, muscle definition and size. Dynamic tension gives these benefits without causing injuries. Because it is nearly impossible for one to get injured because the muscles provide the force. As these muscles tire, the force that provide the tension also decrease. Dynamic tension is a safe and productive form of exercise. Muscle relaxants and other pain-relieving drugs may not be necessary if one properly performs tension exercises.

Studies show that exercising and other physical activities may indeed bring beneficial effects. These benefits may include proper blood flow and improved functions of internal organs. Some medical researches say that endorphins are released every time one engages in physical activities--these endorphins give one a sense of euphoria. Engaging in physical activities properly may become an effective solution for anxiety relief and other forms of stress. Understanding the benefits of exercise and adverse effects of exercise may make a difference in people's lives.
