You know exercise is good for you. You’ve probably known that for years.
So why is it still so hard to actually do it consistently?
There’s a psychological framework that can help explain why changing your activity habits can be difficult. It’s called the Stages of Change model, also known as the Transtheoretical Model, developed by psychologists James Prochaska and Carlo DiClemente in the 1980s.
The model suggests that behavior change isn’t simply a matter of deciding to change and following through. Instead, people tend to move through different stages as they become ready to change.
And progress isn’t always a straight line.
As a physical therapist, I see this all the time. Knowing what you should do is one thing. Being ready to actually do it is another.
So, where are you right now?
Find Your Stage
☐ “I don’t really see exercise as something I need to worry about.”
→ Precontemplation
You’re not currently thinking seriously about becoming more active. That’s okay. This is a normal starting point, not a character flaw.
Next step: Get curious. Notice how your current activity level affects your energy, mood, sleep, or ability to do the things you enjoy.
☐ “I know I probably should move more, but I haven’t decided if I’m ready.”
→ Contemplation
You recognize that becoming more active could help, but you’re also weighing the barriers—time, motivation, pain, or simply not knowing where to start.
Next step: Identify what’s holding you back and what you might gain by becoming more active.
☐ “I’m planning to start something soon—I’ve even looked into a few options.”
→ Preparation
You’re getting ready to take action. Maybe you’ve bought walking shoes, looked up a gym, or decided to start walking after dinner.
Next step: Make your plan specific.
Instead of “I’m going to exercise more,” try:
“I’m going to walk for 15 minutes after dinner on Monday, Wednesday, and Friday.”
Specific plans make it easier to turn intention into action.
☐ “I’ve been consistently active for the last few weeks or months.”
→ Action
You’ve made a meaningful change and are working to maintain it.
This stage can be exciting, but life can quickly get in the way—work, travel, illness, pain, or family responsibilities.
Next step: Focus on consistency rather than perfection. Build support around your new habit.
☐ “I’ve been active for 6+ months and it’s become part of my routine.”
→ Maintenance
Physical activity has become an established part of your life.
That doesn’t mean you’ll never miss a workout. The goal is to recognize setbacks and have a plan for getting back on track.
Next step: Plan for the rough patches before they happen.
No Matter Where You Landed, Here’s the Important Part
There isn’t a “bad” stage to be in. Each stage simply calls for a different approach.
- Precontemplation → Get curious.
- Contemplation → Explore the barriers.
- Preparation → Make a specific plan.
- Action → Build consistency.
- Maintenance → Prepare for setbacks.
The mistake we often make is using the same strategy for everyone.
Someone who isn’t considering exercise doesn’t necessarily need a workout program. Someone ready to start may not need more information—they may need a simple plan.
The right next step depends on where you are.
Setbacks Are Normal
Progress doesn’t always happen in a straight line.
You may start exercising, stop for a while, and eventually start again. You may lose motivation, get injured, or simply go through a busy season of life.
That doesn’t erase the progress you made.
Instead of thinking, “I failed again,” try asking:
“What stage am I in now, and what is the next step that makes sense for me?”
The goal isn’t to get everything right the first time.
It’s to keep moving forward—one sustainable step at a time.
