I go to the chiro once a week and get deep tissue massage every few weeks. Currently I'm contest prepping and both are extremely helpful and beneficial. In the off season I will still go to the chiro once a week, and get a massage once a month.
I have some lower back problems resulting from some pelvic misalignment that I go to the chiro for, it's helped the pain overall and I can definitely feel a difference while training as well.
The massage has been absolutely awesome, I always feel fantastic in and out of the gym the week after. If you get a massage I recommend a good massage therapist, and not a commercial place.
