The black balls are small and light, which makes it easy to take them with you wherever you go!
They are more advanced, and good balls to graduate to after learning all of the basics on the bigger, softer balls.
The black balls are recommended for working in detail and focussing on individual muscles.
You can work your legs, get into tight spots, and roll up both sides of your spine at the same time. They can also be used for “in Bed” Routines.
