In addition to Voodoo Flossing and Banded Work, rolling out your triceps on a barbell is an excellent way to free up range in your elbow, alleviate pain and improve your movement quality.
Spend about 20-30 seconds working above and below the eblow, on the top and bottom side of the forearm/upper arm. If you find any particularly gnarly spots, hang there for a bit and flex and extend the elbow joint.
Try it and let us know you get on!
