using a DUOBALL
This is more of an advanced technique to mobilize the lumbar spine. The Duoball is the perfect tool here, as it allows to deeply release the muscles around the spine down to their insertion on the pelvis. Make sure to avoid any kind of pain radiating down to the legs with this exercise.
Duoball – the Duoball is the evolution from the classic „two tennis balls in a sock“ concept. It is a great tool to deeply release muscles and the fascia. It has some advantages over a classic foam roller like the Blackroll, as it allows to roll closer to the bony tendon insertions like on the Achilles or the patella tendon. The release is also more intense – a must-have for advanced users!
