When we think about the benefits of exercise we often think about calories burned, increasing strength, or better cardiovascular function. But what about our hormones? Can we have better hormone function because of exercise?

If you are wanting to drop some excess body fat, or concerned about looking and feeling younger, then consider some form of resistance training.
