From Trina - Getting a massage after working out is more beneficial to your body. It helps flush lactic acid buildup out of muscle fiber and reduce recovery time. It also depends on whether you are competing, in which case an invigorating pre-competition massage is great to get you ready, then a post massage to flush toxins and help relax and recover are beneficial.

From Michael - Massages are beneficial Pre or Post workouts.  Pre-workout allows for greater range of motion and strength. Post workout allows the muscles to recover faster and prevent pain from lactic acid build-up.
