Sports massage can be helpful both before and after a workout, but the purpose is different.
Before exercise, a lighter massage can help warm up the muscles, improve flexibility, and reduce the risk of injury. It prepares the body for movement.
After exercise, a deeper massage can help reduce muscle tension, improve blood circulation, and speed up recovery. It also helps reduce soreness.
Choosing the right timing depends on your goal. If you want to prepare your body, go before. If you want to recover faster, go after.
