The Ready State Virtual Mobility Coach is like having a virtual Kelly Starrett in your pocket.
Putting the opposite knee on your forearm and smashing it is definitely effective but does not feel good at all. Voodoo bands are also the one thing that specifically helps with my golfer/tennis elbow even though I don’t play either of those sports it’s mostly from ring pullups and KB swings. I would imagine my forearms become quit crappy after lots of deadlift as well. Anything grip intensive honestly.
