Sports/Deep massage can be done clothed or not depending on the objective and duration.
30-minute sessions are beneficial pre or post sporting events to increase circulation and flush metabolic toxins and are done clothed.
Sessions of 60-90 minutes are done between physical efforts or as maintenance to allow the body to receive more focused attention and are done disrobed (keeping your underwear). Deep pressure is used on tight muscles but always within one’s comfort level. It shouldn’t hurt, but it might be a bit more uncomfortable than a classic Swedish massage. You should always feel free to speak up if the pressure is too much for you. .
Communication is the key!
It’s important to drink a lot of water after a deep tissue massage to help flush lactic acid out of the tissues.
