Exercise vs Training
Training is physical activity with a long term goal in mind. Specifically designed workouts are produce to reach a desired result. Training is accumulated and specific stress adaptations that produce specific and desired result. If a program of physical activity is not designed with specific goals to get you stronger, faster, or better conditioned, then you do not get to call it training, it is just exercise.
Exercise is physical Activity for it's own sake, a workout for the effect it produces today. Non-specific and short term goals of moving around, burning calories, and getting sweaty, are the main focus for that specific workout. Regular exercise has minimal stress adaptation to produce tangible changes in strength, muscle building, or increased performance, but exercise is great for general health and wellness. Exercise is definitely better than sitting on your butt all day.
