a. true
b. false

True

Explanation:

The torso of a runner should be fully stretched and lean slightly forward while running. This positions the body's center of gravity farther forward, which facilitates thrust and may even decrease the strain on the knee joint.

Running with your body slightly bent forward is a way to improve the biomechanics of running. When we do this, we position the body's center of gravity farther, which facilitates thrust and may even lessen the strain on the knee joint. Think of a shooting practice: when you will stop the movement, ie stop it, your body will lean backwards. So a forward bend does the opposite, helps speed up.

yes. even my brother has more hair than that.
