With exercise small changes can produce surprisingly large results. A change of direction each time you floor tap not only provides some variation but it also challenges your body’s tendency to fall into an optimized routine that minimizes the energy required to do anything. This makes the exercises physically challenging but there are other, hidden benefits to this: by changing direction each time the exercises become harder from a cognitive recognition perspective. In short they challenge your brain, forcing it to work harder to adapt. Exercise helps achieve significant gains in mental clarity, coordination and even raise IQ points.
