What happens when you push your hands against a wall for 30 seconds?

Answer 1

When you push your hands against a wall for 30 seconds, your muscles engage and generate tension to counteract the force. This sustained contraction can lead to a buildup of lactic acid, causing a sensation of fatigue or discomfort in the muscles. Afterward, you may also experience a feeling of relaxation or slight weakness in your arms as the muscles release the tension. Additionally, this activity can improve muscular endurance over time with consistent practice.
