Massages are an important part of a fitness programme especially when training with resistance. They have physiological benefits and are a great way to treat yourself after hard workouts.
According to a recent study by at McMaster University, deep tissue massage after an intense workout caused muscles to enlarge and grow new mitochondria.
Schedule your massage according to your workout plan. Ideally, if you train for 5 days a week, then a weekly massage a week would be best.
If you workout 4 days a week, get a massage every 2 weeks and if you train 3 days a week, a monthly session will suffice.
This is by no means set in stone and you should listen to your body.
