Let’s start with the most important point: telling people to exercise rarely works, not because you haven’t said enough, but because you’re talking to the wrong “stage." Psychology research shows that when someone changes a habit (starting to exercise, quitting smoking, or controlling their diet), they go through five stages, and what works at each stage is completely different. Throwing an exercise routine at someone who hasn’t even considered moving is like pitching a loan to someone who isn’t looking to buy a car. It’s bound to fail.
This is a follow-up to Do 80-Year-Olds Still Need to Exercise?, written for those of you exhausted from trying to talk your family into moving.
Figure out where they are first
Take “regular exercise” as an example. The five stages look like this:
- Haven’t thought about it: “I’m in my 80s, why would I exercise?” No intention of changing at all.
- Thinking about it: “I mean, I’ve been meaning to move around a bit…” The thought is there, but no action yet.
- Getting ready: They’re asking questions, bought shoes, looking into classes, and want to start soon.
- Taking action: They’ve actually started exercising regularly, but for less than six months. They could quit at any time.
- Making it a habit: They’ve kept it up for over six months. Exercise is now part of their life.
Key Concept
The things we love doing most—making routines, setting plans, getting them to commit—are actually tools meant for steps 3 and 4. But most of the family members causing you headaches are still at steps 1 or 2. When the tool doesn’t match the stage, talking more is just wasted effort, and it hurts the relationship.
Say different things at each step
- They haven’t thought about it (Step 1): The only goal here is to get them to “start thinking.” You can chat about the benefits of exercise and the risks of being sedentary, but keep the tone as sharing, not commanding. If they say they don’t have time, tell them walking can be broken down into 10-minute chunks. Get them to think about “what they could do if their legs were stronger,” like going grocery shopping on their own or attending their granddaughter’s wedding. Do not bring up an exercise routine here.
- They are thinking about it (Step 2): Turn “thinking” into “daring.” Brainstorm together to remove their concerns (fear of falling, fear of getting tired). Emphasize that even the smallest step counts: “Just walk with me to the end of the alley for now.”
- They are getting ready (Step 3): Now it’s time to make a plan. Together, set a goal so small it can’t fail, and be as specific as possible: “Walk with mom for 15 minutes every day after dinner.”
- They are taking action (Step 4): The focus is keeping them going. Praise specific progress, switch up activities so they don’t get bored, and find them a workout buddy—that works best.
- They’ve made it a habit (Step 5): Give them occasional encouragement and exercise with them. That’s enough.
Relapse is Normal
Stopping or slipping backward is a normal part of the change process, not a total failure. Don’t lecture them with “I knew you’d quit halfway.” Just pick up from whatever step they fell back to.
Why small goals matter so much
Because the “confidence that I can do this” grows slowly over time. If someone experiences failure when their confidence is still fragile, they will retreat entirely, which is worse than never starting. That’s why starting goals need to be so small they’re almost impossible to fail. Not “exercise three times a week for 30 minutes each time,” but “walk to the end of the alley with me today.” Succeed once, gain a bit of confidence, and slowly add from there.

The bottom line first: “Telling people to exercise” rarely works, not because you haven’t said enough, but because you’re addressing the wrong stage. The Transtheoretical Model breaks the process of changing a behavior down into five stages, and what you should do at each stage is entirely different. This is the framework behind why patient education so often turns into preachy nagging, as mentioned in Do 80-Year-Olds Still Need to Exercise?.
The Five Stages
Using “regular exercise” as an example, the boundaries between the five stages primarily look at intention (the earlier stages) and action (the later stages):
| Stage | Definition |
|---|---|
| Precontemplation | No intention to start regular exercise within the next 6 months |
| Contemplation | Intends to start within the next 6 months |
| Preparation | Intends to start within the next 30 days, usually has taken some specific steps (bought shoes, asked at the clinic) |
| Action | Has been exercising regularly, but for less than 6 months |
| Maintenance | Has been exercising regularly for over 6 months |

The Key: Assess the Stage First, Then Decide What to Say
The older patient saying, “I’m in my 80s, why would I exercise?” is in precontemplation: they have no intention of changing. Meanwhile, the things we’re most used to doing—drafting exercise plans, writing routines, signing contracts—are actually tools meant for the preparation to action stages. If the tool doesn’t match the stage, talking more is just wasted effort.
Let’s clear up a common misunderstanding here: which stage is “explaining the consequences of not exercising and the benefits of exercising” actually for? The answer is precontemplation. Discussing consequences and benefits with someone who has no intention of changing is exactly one of the methods used to push them from precontemplation to contemplation. So the point isn’t “don’t talk about consequences,” but rather “talk about consequences to raise awareness of the problem, not as a command demanding they start exercising tomorrow.”
What to Do at Each Stage (This is Crucial)
Below are the intervention strategies corresponding to the transitions between each stage, adapted from ACSM Box 12.1.
Precontemplation → Contemplation
The goal is to raise awareness and loosen the “this has nothing to do with me” mindset:
- Provide information on the benefits of regular exercise.
- Address their perceived barriers. For example, if they say they “have no time,” tell them “exercise can be broken down into shorter, accumulated bouts; you don’t have to do it all at once.” (That’s right, handling “no time” is for this stage, not later.)
- Ask them to imagine what it would feel like to be active, and emphasize short-term, easily achievable benefits: sleeping better, feeling less stiff, having more energy.
- Explore who is affected by their lack of exercise, such as their spouse or children.
Contemplation → Preparation
They’re starting to waver. This stage is about turning “wanting to” into “daring to”:
- Work together to find specific solutions to overcome barriers to exercise.
- Assess their confidence (self-efficacy), and start using techniques to build it up.
- Emphasize that even a very small step counts.
- Encourage them to view themselves as a “healthy, active person.”
Preparation → Action
Now it’s finally time to “make a plan”:
- Draft an exercise plan together that fits their goals, using a goal-setting worksheet or contract to turn it into a formal commitment.
- Use rewards to reinforce every step they take.
- Teach them self-monitoring, such as logging exercise time and distance.
- Continue discussing how to overcome whatever hurdles they feel are in their way.
Action → Maintenance
They are already moving. This stage is about preventing them from quitting halfway:
- Provide positive, specific feedback on their progress.
- Look for different types of activities together to prevent burnout.
- Encourage them to find workout buddies, or even lead others in being active.
- Discuss what rewards can be used to maintain motivation.

One important reminder: The stages are not a one-way street. A person might slip backward during their attempts (reducing or stopping exercise), but this doesn’t mean everything has to start over from scratch, back to precontemplation. They can pick back up from any stage, and our role is to help them positively restart.
The Three Underlying Mechanisms
Besides the five stages, the Transtheoretical Model has three very practical concepts that help us understand “why” we do it this way.
1. Ten Processes of Change: “Thoughts” Early, “Behaviors” Late
To push someone forward, there are ten specific methods (processes of change), broadly divided into two categories. The earlier stages (precontemplation to preparation) primarily use “cognitive/emotional” methods, while the later stages (preparation to maintenance) primarily use “behavioral” methods.
| Type | Method | Plain Language |
|---|---|---|
| Cognitive/Emotional (Early) | Consciousness Raising | Letting them know about “not exercising” and its consequences |
| Cognitive/Emotional | Dramatic Relief | Evoking an emotional response to those consequences (worry, regret) |
| Cognitive/Emotional | Environmental Reevaluation | Thinking about how this affects the people and environment around them |
| Cognitive/Emotional | Social Liberation | Noticing opportunities in society that support change (community trails, health trends) |
| Cognitive/Emotional | Self-Reevaluation | Connecting “who I am” to this behavior (imagining the active vs. inactive self) |
| Behavioral (Late) | Self-Liberation | Making a commitment to change (setting goals, going public) |
| Behavioral | Reinforcement Management | Using rewards to reinforce each achievement |
| Behavioral | Helping Relationships | Building a support system (family, friends, peers) |
| Behavioral | Counterconditioning | Substituting positive behaviors for old habits |
| Behavioral | Stimulus Control | Managing the environment, avoiding situations that encourage inactivity |
This explains why constantly “drafting routines” (a behavioral method) for someone in precontemplation doesn’t work—they are still in the stage where they need to “loosen their thoughts.”
2. The Scale of Pros and Cons: Decisional Balance
Decisional balance refers to the tug-of-war in someone’s mind between the “pros of changing” and the “cons/hassles of changing.” This scale tips as the stages progress:
- Precontemplation: Cons > Pros. They feel the hassle and effort of exercising outweigh the benefits, so they don’t bother moving.
- Contemplation: The two sides draw closer.
- Preparation: Pros and Cons are roughly equal.
- Action, Maintenance: Pros > Cons.
So what patient education should do early on is actually help them add weight to the “pros” side and dismantle the concerns on the “cons” side (like “no time” or “fear of injury”). Only then will the scale slowly tip toward change.
3. Confidence Grows Along the Way: Self-Efficacy
Self-efficacy (the confidence that one can do it) is lowest in precontemplation and highest in maintenance, increasing steadily along the way. This is also why the transition from “contemplation to preparation” specifically emphasizes building confidence early. Confidence is still fragile here; if they encounter failure before their confidence is solid, it will be crushed, causing them to fall back to an earlier stage. That’s why you have to start with goals so small they’re almost impossible to fail.
Back to the 80-Year-Old Patient
He’s in precontemplation. So the right approach isn’t forcing a workout routine on him, but using precontemplation methods first: validate his habit of walking every day, get him to think about what else he wants to do, and gently dismantle concerns like “no time” or “fear of injury,” making him willing to take a step toward “contemplation” on his own. As for how exactly to have that conversation, you can check out my notes on motivational interviewing.
