Question

Try to stretch your muscles with and without help and see the difference.

Answer 1

Stretching with the help of another person is called passive flexibility, while stretching without help is called active flexibility. In passive flexibility, an external force produces the stretch, so the range of motion around the joint is greater. In active flexibility, the person uses only his or her own muscle action, so the range is smaller. This is why the range of motion is greater in passive stretching than in active stretching.
