The Falling Lunge was developed by Professor Janda to train the Reflexive and Proprioceptive systems.
For the lunge to be effective, it needs to be trained with ideal posture.
The power bands give great feedback to achieve this ideal!
I describe how the role of reflexes is to be present to be fast acting via contraction speed to protect the joint.
