As we age, why does weightlifting/resistance training make our bodies stronger/durable compared to laborious jobs that weaken our bodies

Question

Both tend to put stress on our bodies, why does one make us stronger and the other makes it weaker as we get older

In: 16

Answer 1

? The difference between the two is the type of stress being applied to the body. Strength training puts a physical stress on the body, which causes the muscles to adapt and become stronger. Cardio exercise puts a metabolic stress on the body, which can cause the body to become weaker over time as the muscles become less efficient at using oxygen and producing energy. As we age, our bodies become less efficient at recovering from metabolic stress, so the benefit of cardio exercise decreases with age. Strength training, on the other hand, can help to maintain and even increase muscle mass and strength as we age, allowing us to remain strong and healthy.
