Do you feel like a slacker on the mornings you snoozed through your workout and
missed it altogether? You’ve heard sayings like, “while you’re sleeping, someone

ridiculous hours to train and deprive themselves of sleep. They may be getting
more training time in, but are they really improving their fitness and health?
