you only have to do it about 40 times- can be fast if you wish i guess- i have condition which causes weakness in muscles, and it’s hard to hold my arms up but i can just barely manage about 50 times- quick ones- and it has ‘helped’ so far- we’ll see if repeated times mean more relief-
When I do it, I only need about 4 or five times. Ringing goes away for months.
