What is temptation bundling?
Temptation bundling means pairing something you want to do with something you should do, and only allowing yourself the want while you do the should. The want is an instant pleasure: a gripping audiobook, a show, a favorite coffee. The should is a habit with a delayed payoff: exercise, chores, admin, studying.
The term comes from Katy Milkman, a behavioral scientist at the Wharton School, who tested it with gym members in 2011 and published the results in 2014. The idea works on present bias: we overvalue rewards we get now and undervalue rewards that come later. Bundling moves some of the reward into the present.
Two versions exist. A strict bundle keeps the want locked to the should ("this podcast only on the treadmill"). A loose bundle just pairs them ("I listen to podcasts while I clean"). The strict version is what the original study tested and what makes the want pull you toward the should.
Temptation bundling examples: 40 pairs
Each row is one bundle. Read it as: I only get the want while I do the should. Pick one that fits your life before you invent your own.

How do you build a temptation bundle?
- List your wants. Write five things you enjoy and tend to overdo: a show, a podcast, a type of coffee, a game, a snack. These are your bundling currency.
- List your shoulds. Write three habits you keep putting off. Be concrete: "walk 30 minutes", not "get fit".
- Match them. A good pair can happen at the same time and place. Podcasts fit walking; a show fits a bike or folding laundry; a pastry fits a planning session at a cafe. Avoid wants that distract you from the should if the should needs your full attention, such as music with lyrics for hard reading.
- Set the rule. Decide how strict it is: "I only listen to this audiobook while I walk." Write it down.
- Attach it to a cue with habit stacking. Plans that say when and where you will act are followed through more often, with a medium-to-large effect across 94 studies (Gollwitzer and Sheeran, 2006), so give the bundle a fixed moment: After I put the kids to bed, I will walk on the treadmill while I watch the next episode. The habit stacking builder turns this into an "After I…, I will…" card with a hard-day version you can print.
- Make the want easy only in the right place. Download the episodes on the phone you take to the gym, keep the special coffee beans at the office, put the novel on your pillow.
- Track it for a few weeks. Tick each day you did the should. The habit tracker gives you a simple grid.
A worked example: Priya's evening walk
Priya, 34, wants to walk four evenings a week and keeps skipping it. She loves a crime podcast and listens to it on the couch.
- Bundle: the crime podcast only while walking.
- Habit stack: After I load the dishwasher, I will put on my shoes and walk for 25 minutes with the next episode.
- Hard-day version: walk around the block for one episode segment, about 10 minutes.
- Setup: episodes downloaded, earbuds in her jacket pocket by the door.
- Week 1: four walks, mostly because she wanted to know what happened next.
- Week 3: a long weekend away breaks the run, which is what happened in the original study after the Thanksgiving break. She restarts with the hard-day version on Monday.
The bundle did not make walking effortless. It made starting easier on the evenings when the couch was winning, and the cue made it automatic enough to survive a missed week.
What does the research say about temptation bundling?
The 2014 gym study
Milkman, Minson and Volpp (2014), published in Management Science, followed 226 students, faculty and staff at a US university for about nine weeks. One group could listen to tempting audiobooks only on iPods kept at the gym. A second group got the audiobooks on their own devices and was encouraged to listen only at the gym. A control group did not get the audiobooks.
At first, the gym-only group went to the gym 51% more often than the control group and the encouraged group 29% more. The effect shrank over time, especially after the Thanksgiving break. When the study ended, 61% of participants said they would pay for gym-only access to audiobooks, which suggests people want this kind of self-imposed rule.
The 2020 large follow-up
A much bigger test by Kirgios, Milkman, Duckworth and colleagues, published in Organizational Behavior and Human Decision Processes (volume 161, 2020), ran with 6,792 gym members in a four-week exercise program. People who got a free audiobook and encouragement to bundle were 10 to 14% more likely to work out in a given week, and made 10 to 12% more weekly gym visits than the control group, during the program and up to 17 weeks after it ended.
Two caveats are worth knowing. The effect is far smaller than the famous 51%, which is normal when a study gets bigger and more realistic. And compared with getting the audiobook alone, the extra encouragement to bundle added only a modest benefit; the authors suggest that handing someone an audiobook already hints that they should bundle.
What the research does not show
Both studies were about exercise and gyms. There is no strong evidence yet for chores, studying or money tasks; those examples rely on the same idea, not on a direct test. And bundling does not replace the basics of habit building: a fixed cue, a small first step and a plan for missed days. For those, see how to be consistent and the evidence in the Atomic Habits research summary.
Temptation bundling vs habit stacking vs rewards
| Technique |
What it does |
Example |
| Temptation bundling |
Pairs a pleasure with the habit, at the same time |
Podcast only while walking |
| Habit stacking |
Ties a new habit to an existing one, as a cue |
After coffee, I walk |
| Reward after |
A treat once the habit is done |
A bath after the budget check |
They work best together: the stack decides when, the bundle makes it pleasant, and a tracker shows your progress.
Common mistakes
- Cheating on the want. If you also watch the show on the couch, it stops pulling you to the treadmill. Keep the rule simple enough to keep.
- A want that ruins the should. A show during hard studying splits your attention. Save heavy wants for physical or routine tasks.
- A want you would not miss. If you do not care about the want, the bundle does nothing. Pick something you look forward to.
- Bundling with a treat that undoes the goal. A large dessert every gym visit is a trade, not a bundle. Small and sustainable wins.
- No plan for breaks. Holidays and illness interrupt bundles, as the 2014 study saw. Plan the restart in advance.
