You're fit if you can:

  • Carry out daily tasks without fatigue and have ample energy to enjoy leisure pursuits.
  • Walk a mile or climb a few flights of stairs without becoming winded or feeling heaviness or fatigue in your legs.
  • Carry on a conversation during light to moderate exercise such as brisk walking.
  • If you sit most of the day, you're probably not fit. Signs of deconditioning include feeling tired most of the time, being unable to keep up with others your age, avoiding physical activity because you know you'll quickly tire and becoming short of breath or fatigued when walking a short distance.
