The long answer is that exercise isn't only helpful for health, it is also absolutely required. Most of our muscular, skeletal, and nervous systems require continuous work to keep them usable.
Let's look at what happens when you don't exercise.
The nervous pathways used to perform basic movements degrade. As a result, our nerves themselves weaken and are more prone to injuries.
Bone density, and thus bone resistance, degrades. Bones become more fragile and prone to breaking. This is how osteoporosis and arthritis come to be in elderly people.
Muscles in our body weaken, shrivel up and reduce in size. As a result, they're more prone to injuries. Even more, as muscle is mostly protective in the body, the spine and vital organs are also a lot more injury prone. Eventually, weak lower back muscles are what cause most elderly people to have severe back pain.
Testosterone levels in the organism decrease and hormonal imbalances ensue. As a result, we become more irritable, less active, less excited about things. Lethargy and a constant sense of tiredness come to be. Depression is more likely, as well as storage of body fat. 6K viewsView 6 Upvoters Related Questions (More Answers Below)
