GROUND REACTION FORCE
What is Ground Reaction Force (GRF)? Newton's 3rd Law of Motion states that "For every action there is an equal and opposite reaction." According to that, when we walk or run, every time our foot lands, there is what is called a 'Ground Reaction Force' produced. Some go as far as to claim that "The ground reaction force is an important external force acting upon the human body in motion. We use this force as propulsion to initiate and to control the movement." (Read more) It could be considered a pretty important external force acting upon the body in motion....

SIGNIFICANCE OF PROPER BODY POSITIONING & BODY ALIGNMENT
Did your mom ever tell you to sit up straight and stop slouching? Did your grandma tell you to keep your head up and not look down? If they did - thank them every day, because lots of people never get such valuable advice and enough pressure to follow through and maintain.

As human history progressed and the development of modern creature comforts like secure housing and continuous food supplies insulated us from the day–to–day vagaries of life in the wild, the need for the highest levels of perception were eroded...

SWIMMING TECHNIQUE: TO ROLL OR NOT TO ROLL
"To do or not to do" - same topic different sport, but much like the highly debated "push off" in running, the rolling of the body in swimming is a no-no. There are several reasons for that. Number one is the fact that rolling takes away from falling (can't use gravity without falling), i.e. rolling interferes with movement forward. Need we say more? From the Pose Method point of view, swimming is nothing but change of support in water. Due to the nature of movement happening during the change of support, minimal to no body rotation is desired in order...
