A good massage relies on a number of techniques. In my massage therapy practice in York I find myself paying a lot of attention on releasing muscular knots. This requires massaging a particular point to an appropriate depth (not too deep or to gentle), and focusing on that specific area until that knot has fully or partially released.
However, a generally tense muscle can require massage along it’s entire length. This, again, needs focused attention. Going too quickly can result in the muscle not being released.
Only by “listening” to the muscles and the body in general, can one give an appropriate massage.
