Engaging in physical fitness provides several health advantages, such as reducing anxiety, improving blood cholesterol levels, lowering the risk of heart disease, losing weight and preventing osteoporosis, according to Joelle Dedalus for AZCentral.com. Drawbacks of exercise include the cost of gym memberships and home equipment, as well as the time required for training.
Additional benefits to exercising include lowered blood pressure, diabetes prevention and a reduced risk of developing several types of cancer, notes Crystal Welch for Live Well from JillianMichaels.com. Many modes of physical fitness are excellent for improving form, but this can be an impediment for people if they are uneducated about proper technique and can cause injury to joints, muscles and tendons.
Another benefit of working out is increasing one's intensity to a moderate or intense level so maximum results are gained by improving heart and lung strength. This can function as a disadvantage if a person pushes his body too far and burns out his muscles; becomes dizzy or nauseous; or develops injuries, explains Welch. A thorough workout program should be designed to hit all of the major muscle groups, including the back, arms, abdominals, legs and chest. This requires a time commitment of at least 150 minutes each week, and many people may not have this time available in their schedules, which is another disadvantage of exercise.
