FITT Principle:
Frequency = How often you exercise
Intensity = How hard you exercise
Time = How long you exercise
Type = What kind of exercise you do
Cardio-respiratory example :
F = 3-5 times a week
I = Target Heart Rate or (Fast, Slow) or (sprinting, jogging, mile pace)
T = 20 minutes or more
T = Aerobic Activities (Running, cycling, swimming, etc.)
Muscular Endurance example:
F = 2-4 times per week
I = moderate/vigorous
T = 9 or more repetitions or 30 seconds or more
T = Sit-ups or plank. (Exercise that fits the Time category above)
Muscular Strength example:
F = 2-4 times per week
I = moderate/vigorous
T = 8 or less repetitions
T = Pull-ups or pull ups (Exercise that fits the Time category above)
Flexibility example:
F = daily recommended
I = mild pull, never pain
T = 10 seconds or more
T = Sit & Reach, trunk lift, dynamic stretche
