Physical activityExercise: Any kind of muscular work that requires more energy than resting.
Four main aspects: Intensity, duration, frequency, type
Fitness: Synonym for merits/features people possess, which enable them to do physical work (endurance, strength, flexibility, coordination)
Training: Systematic, purposeful, regular exercise aiming at maintaining or improving fitness, in one or more ways.

Exercise - intensityLow intensity "exercise": Resting, low energy usage (car-addicted (overweight) office workers, sedentary people)
Moderate intensity exercise: Energy expenditure 3-6x rest (brisk walking, gardening, house cleaning - oh yes!, easy jogging/cycling/swimming
High intensity exercise: >6x more energy than rest - now you´re working out some sweat! Snow-shuffling (parents, money!), mountaineering, cross-country skiing, running

Children/adolescents: At least 60 min medium-high intensity exercise daily. Max. 2 h computer/screentime a day
Adults: Medium intensity exercise at least 30 min/day
Elderly: Same as adults. Strength training important (prevents falls)

Low intensity training
