Remember The 40% Rule

Research suggests that statement – the 40% rule – has some truth. We are often physically more capable than we perceive ourselves to be. For instance, researchers found that subjects who were given a placebo but told it was caffeine were able to lift significantly more weight than those who were really given caffeine.

There’s a reserve tank within us that we never really tap on. Only by pushing ourselves to our limits — and then breaking them — can we reach our full potential.
