I've found that when people feel a massage has been painful & left bruises, it's the specific work they found uncomfortable. (Trigger point therapy, muscle stripping -- anything with thumbs.) In a swedish massage, I leave all of those techniques out of the mix. If people really just want to relax, then my goal is to soothe with the strokes instead of work out specific areas of tension. That means I get very creative with varieties of effleurage. : If I ever do use my thumbs in a stroke, I hold way back on the pressure, so really, it's just thumb effleurage. I don't try to work out knots at all. I also don't use my forearms at all on swedish massages, since it's too easy to use strong pressure with the forearms. This means there's a lot of repetition of strokes, which can be a little boring for the therapist, but clients who like relaxation massage love that repetition.
