It's important to give your body time to rest and recover after any form of physical activity. Make sure to warm up before exercise, vary your routine to avoid overworking specific muscles, and listen to your body's signals if you start to feel pain or discomfort. If you're concerned about any physical changes in your chest, it's best to consult with a healthcare professional for personalized advice and guidance.
