Active stretching or static-active stretching is a part of exercise in which the body is stretched to it's maximum by holding a position with no assistance. For example, holding a legs up free without any support. The active stretching increases the strength and flexibility of the muscles.
The disadvantage of the active stretching is that it has a very high risk of injury. This is because of the fact that it is done without any support hence, the body part may experience a downfall during the exercise and may get injured.
Increasing the physical demands on the body over time to improve abilities is known as <u>"progressive overload".</u>
Progressive overload implies that you are persistently expanding the demands on your muscles so as to make gains in their quality, size and perseverance. The harder you work them, the more grounded you move toward becoming. It sounds evident I know, however for some individuals, its simple to dismiss it.
There might be a load you struggle to lift at first. Following up to 14 days, you figure out how to lift it. Awesome. With progressive overload, it doesnt stop there. Add more load to drive your muscles considerably more, to lift greater loads. Its this basic idea that resistance preparing is based upon.
