ankle weights can increase the energy you burn while walking, they may strain the ankle joint and leg muscles, which could increase your risk of injury.

Answer 2

Our running and walking ,works on the Newton's third law of motion,"every action has a same amount of reaction in the opposite direction."

When we apply force on the ground with our feet, the ground also applies a repellent force on our body.
