The Ready State Virtual Mobility Coach is like having a virtual Kelly Starrett in your pocket.
It’s not necessary to warm up for mobilizing.
Your tissues may however be more receptive and responsive if you are warmed up first especially when working on the sliding surfaces and muscle dynamics.
if you jump into something cold and it feels sketchy then go ahead and break a sweat and see if that helps.
I suppose it’s easier to say being warmed up won’t hirt anything.
