I never thought much of exercise mantras, probably because I have never been very competitive. I love a good running race or triathlon, but I guess I was never fast enough to get SUPER aggressive with it. After a complete switch in focus of training (trying to keep above MS and take care of my body at the same time), I realized a mantra was just what I needed.
The other night was my longest run to date (3.5 mi-I know sad), and at 3 mi I felt completely exhausted and a bit upset that my body was failing me. To myself I repeated,"My body is able," over and over until I finished my run. I was amazed at how that allowed me to dig deep and finish. I finally see what they mean by sports psychology.
