This is a prototype of a new bar called a Tsunami bar. It has a patent pending and should be available in 4 to 5 weeks at elitefts. This is similar to the bamboo bar in that it works by using oscillating kinetic energy. There have been some preliminiary studies done on it with benching, and it increased muscle activation by 20%. No data available yet on squats. More options for max effort work is a good thing.
