Everyday each of us live at a certain level of activity. The "BAR" is the beginning point or baseline. At this point we eat, sleep, and work (job, household chores). Looking at the photo above, this is the "blue box" with the "black line." When we live here all the time, the chance for injury during those daily activities increases because you are at your maximum ability.
Raising the BAR. Exercise outside of daily activities and routines increases your ability to perform. Thus, your injury resistance increases because your strength, stamina, energy, and endurance for daily activities far exceeds your baseline. You have effectively raised the bar. This new level of performance decreases your risk for injury with all activities that are within your baseline.
Never settle. Always push yourself to be better, stronger, more resilient.
