Is it true that excercising in the mornings.....?

help your metabolism speed up for the rest of the day?
Yes it does slightly. Another way to increase metabolism is doing High Intensity Interval Training, it raises your metabolism for the rest of the day. Another benefit is that testosterone is highest in the morning, making gaining muscle a little easier.
sounds good, plus if your outside the pollen and smog dont have a chance to rise yet.
I often do exercises in the morning, and I find that it really does something to the metabolism of the body. And I will feel hungry in a short time. I really love this feeling.
Yes, When we wake up in the morning, our bodies have healed up after the previous day
