A few years ago, I got a sports massage after
a triathlon.
My masseuse gave me a rough time because I was "fighting"
the massage instead of fully relaxing.
She said that learning to fully relax muscles after a workout
is extremely difficult, and most people don't get the hang of
it until after they've had a few massages.
Dreyfus has absolutely no difficulty with 100%
relaxation.
It's almost like he melts into the floor, without the slightest
bit of muscle tension in his body.
