This is not a trick question... Are you a shark?
Here's what I mean by that. Sharks don't need motivation. They are up early hunting prey, being scary and reminding everyone they're a freakin' shark.
How does that relate to your fitness and physical rehabilitation. EVERYTHING.
You have a choice every morning when you wake up. You can either chase your goals or succumb to excuses. Your lack of fitness is something you have absolute control over. All you have to do is decide what you want and go after it.
If it was easy then everybody would do it. You may be facing a significant amount of stress in your life. You might even have injuries that you are trying to recover from. While those may be real challenges, will you let that define you?
In one way or another we are all a 'hot mess' but you don't have to live there.
I'd love to hear your story of what challenges you are facing. How can we help you?
