For storage purpose you can coil the belt by holding it on the two sides, and turning one hand inwards, the other outwards.

If you feel resistance, STOP!

It should coil easily (in three loops)

Uncoiling: find the outermost circle, and slowly start to straighten it out. The Belt will uncoil on its own

If you feel resistance, STOP!
