Many people are looking for an activity that will improve them in every way possible; weightlifting is the best activity in the world for such goals! Weightlifting has many benefits and can improve the quality of life for anyone who can do it. Weightlifting is one of the activities that, combined with other exercises and a proper diet, will improve overall health, physical performance and mentality. Above all, the health benefits of weightlifting are numerous and immense. Weight lifting increases muscle strength and also increases bone density. Increased bone density is one of the most beneficial side effects of weightlifting (Sidrah). During weightlifting and other weight-bearing exercises, the tension placed on the bones by weight and muscle contraction makes the bones denser and stronger (Sidrah). Building denser bones is extremely important for older adults and especially older women. Osteoporosis is the progressive thinning of bone mass and bone density (“osteoporosis”). Osteoporosis is a very common disease among women and it is estimated that in the United States of America, approximately 1 in 5 women over the age of 50 have osteoporosis (“osteoporosis”). At least half of women over the age of 50 will experience a fracture of a major bone such as the hip, spine, arm or wrist (“osteoperosis”). Osteoporosis is a very painful, debilitating and even fatal disease that can be prevented through a good diet and, above all, physical activity such as weightlifting. Studies have shown that the risk of osteoporosis is lower in more active people and particularly in those who participate in activities such as weightlifting (“Bone Builders”).
