Most of my active clients ask me if it is okay to exercise after their massage session. Generally, I encourage people to wait 24 hours before doing any vigorous activity. Examples of vigorous activities are running, weightlifting, or other high-intensity workouts. Engaging in vigorous activity less than 24 hours after your massage session has the risk of increasing post-massage soreness, delaying your recovery time, and potentially even compromising the effectiveness of the soft tissue work.
Light to moderate exercise for someone who exercises regularly, on the other hand, can be a good thing after massage. A brisk walk or even some laps in a pool can help to flush out toxins released during the massage as well as to keep muscles healthy and elastic.
Whether an individual chooses to engage in light physical activity after massage or not, you should always remember to drink plenty of water. I encourage two liters of water in the next 24 hours so as to continue to flush out the body. Get plenty of sleep and eat a healthy diet, rich in fruits and vegetables and minimal in sugars.
