Exercise as Snack
If cumulative snacking can cause unwanted weight gain could it not be true that moments of exercise throughout the day might be beneficial in creating the opposite?
A pushup here, stretch, short walk, situp or two...won't it all add up at the end of the day burning calories and adding tone to the muscles? Realize that full sessions of exercise are needed to create strength and endurance. But I would think these small easy steps throughout the day would have to add up to real improvement.
