Wouldn't you be able to keep exercising every day? In that case, exercising every day can help. Huh?
On autopilot
When you exercise every day, it becomes a habit and habits are easier to maintain. Just think of brushing your teeth, you do that twice a day, without thinking about it.
Good for your motivation
If you exercise almost every day, exercise also becomes a habit, so you just do it without thinking. If you can't do it a few times, it's easier to pick up sports again afterwards, according to Michele Bridges (trainer for the television program The Biggest Loser in Australia).
