I would say, I probably do about 95% of the cupping myself. The vacuum pump for the cups comes with an extension hose so I can reach most areas, even on my back, myself. However, there are some areas on my upper back, that I can't reach, and I have my wife do those, when she's willing.

The only bad thing about using the extension hose is, you don't get as much suction, so sometimes the cups fall off. If I can reach an area, it works better without the hose.
