An older gentleman comes to the gym with his bottle of oxygen strapped to his back. When I watch him lift weights I always think "That's how I want to be when I'm in my 70s."
I'm impressed by so many different people. A friend with breast cancer who not only keeps running but is training for an ultra marathon. A 60+ year old lady who is in better shape than most 20 year olds. My husband who finds time to exercise even though his schedule is overflowing with work, church, and family responsibilities (not to mention that lengthy honey-do list). An expectant mom who keeps walking through the pain.
All these people help me realize that I have no excuse not to push myself. Who inspires you to keep working hard?
