myofascial release

I'm currently taking a course based on the CrossFit Mobility certification. I'm going to share what I'm learning, and also how I would combine it with yoga for better overall movement and mobility.
The Trigger Point Therapy Kit and GRID Foam Roller. The Theracane. The Power Stick. The AcuBall Kit. Find out why you might need these items and how they will enhance your performance.
New research shows foam rolling can dramatically increase range of motion, without decreasing the strength of an athlete. There's really no reason not to get on that foam roller or lacrosse ball now.
So you've got a foam roller, but do you know how to use it? Do you know what it's actually doing and why it hurts? Here's some info on how to do self-myofascial release (that's what it's called).
