Thanks to @drjohnrusin for the informative explanation, in how to better hack the deadlift, with this pre-activation drill.
I thought I would give it a try. I chose to DL with the Burley USB though, focusing on the eccentric load, pulling that bag a part for lat(core) activation. The USB and the pull of the sand towards earth, keeps the nervous system asking you, wtf?
Thanks @drjohnrusin for your great posts integrating Strength, pre-hab and stellar biomechanics!
I cannot wait to have you out to Seattle, at @sisustrengthhouse .😊
