There have been some great suggestions so far.
First off, stop calling exercise. Instead, take a moment to identify what fitness looks like for you and why you want to be fit. For example, I wanted to be fit so I could enjoy the activities my 20 year-old daughter was doing (crossfit and obstacle mud runs). I didn’t want to just watch her from the sidelines, I wanted to participate with her. My why was deep and emotional and my vision was reasonably clear.
Fitness is being able to do the things you enjoy. To be able to live the life you want. What does fitness look like for you and why does it matter (deep and emotional)?
Now, doing the work is actually just training to be that. To do the races with my daughter I needed to lose body fat (keto helped me do that). I also needed to build strength and endurance. That drove the activities I chose to do. Any time I didn’t feel like training, I asked myself, is this the person I set out to be? Is this the example I want to set for my daughter?
When we crossed the finish line of the Tough Mudder together, it made every bit of training worth it. Not exercise and not workouts. Training. Training to be the person I wanted to be.
