The answer to this question is again, dependent on the individual. Children can use a personal trainer to develop motor control and coordination. Teenagers and young adults often enjoy the benefits of learning how to lift weights safely and age appropriately. Older adults can benefit from a personal trainer to improve their cardiovascular fitness, overall strength and balance to avoid falls.
Also, more active people have a lower risk of heart disease, type 2 diabetes mellitus, stroke, cancer, depression, osteoporosis, and dementia. Also, in a study involving postmenopausal women, there is a strong link between physical activity and bone mineral density. Women who exercise more in their younger years have a lower incidence of osteoporosis after their menopause.
When a person moves, energy is spent, and more oxygen is required. When exercise is done properly, the heart and blood flow throughout the organs of the body is improved. As a result, the delivery of nutrients and disease-fighting cells reach target areas more quickly.
