Pterygium surgery typically takes 30 to 45 minutes. After surgery, patients usually need to wear an eye patch for a day or two. But they can return to work or normal activities (avoiding swimming and eye rubbing) after a few days.
Functional fitness is based on exercises that are specific to your personal functions or daily movements. You could be unconditioned or an athlete and both be using a form of functional fitness as your way to become further conditioned within your exercise regime.
Functional fitness exercises train your muscles to work together and prepare them for daily tasks by simulating common movements you might do at home, at work or in sports. While using various muscles in the upper and lower body at the same time, functional fitness exercises also emphasize core stability. For example, a squat is a functional exercise because it trains the muscles used when you rise up and down from a chair or pick up low objects.
