When people say they're "all thumbs," it usually means they can't manipulate their fingers precisely. If a massage therapist tells you the same thing, get them to work on your body post haste; they must have some powerful digits. Trigger Point Performance Therapy's TP Massage Ball is a way to get strong thumbs to dig in to your sore muscles without having performed daily massages for years.
TP is short for Trigger Point. This massage ball is like a human thumb, with a soft exterior and hard core. Use it to work your trigger points. The core of the ball self-models easily enough, meaning body pressure will take it out of round, and thus it will offer broader, more customized pressure than a harder material would. You should use this ball to massage your body, either by using body weight and gravity or your hand. It can be as simple as placing it in the palm of your hand and using gentle pressure to roll it against your muscles.
The ball can be used on its own, paired with another ball, or added to their Starter Set or one of their Performance Kits. It's easy to use it to loosen any tight, sore spots just about anywhere on your body. The small size makes it easy to use in small spaces, like when you're stuck in a seat in a car or on a plane, and it's easy to travel with.
