To lower muscle tension and pain during and after physical activity, the best approach is to make sure to warm up the heart and muscles beforehand, and cool down afterward.
A proper warm-up increases blood flow to the muscles, enhances flexibility, and prepares the body for more intense activity, reducing the risk of injury and muscle soreness. Similarly, a cool-down helps to gradually lower heart rate and prevents blood from pooling in the extremities. It also aids in the removal of metabolic waste products from the muscles.
Additionally, incorporating stretching before and after exercise can further help alleviate muscle tension and soreness. Remember to stay hydrated and listen to your body throughout the workout.
