Commitment devices are tools that attempt to bridge the gap between a person's initial motivation to perfrom the behavior and the typical pattern of noncompliance as time goes on.
One prominent example is the "Ulysses Pact," where Filipino banking customers were offered the option to enroll in an account where their ability to make withdrawals would be limited. In a study by Ashraf and Karlan (2005), participants with the commitment account saved 81% more than those with typical accounts.
There are many other examples of commitment devices. Temptation bundling is a form of commitment device where people only engage in an enjoyable activity when it's simultaneous with an activity they intend to do more (for example, only listening to a certain podcast or audiobook while walking on a treadmill).
Pre-paying for a service is a basic form of commitment device, and one used by Dan Ariely when he intended to increase his fruit and vegetable consumption. He paid for a year of biweekly deliveries from a local CSA program up-front.
Reducing friction or barriers to performing a behavior is simply making it easier or removing things that may be preventing someone from doing something.
This is a foundational technique in changing behavior, and part of the UK Behavioural Insights Team's 4-point approach ("Make it easy"). That said, knowing where the friction and barriers exist may not always be straightforward, and different groups of people may experience different barriers in different contexts.
Note: It is possible to remove too much friction. In a well-popularized study, a travel booking site found that delays in loading the best deals or travel options actually increased conversions. Similarly, longer input forms in digital interactions sometimes outperform, as people may consider the results more personalized or experience greater cognitive dissonance after having invested so much time in exploring the service.

Financial incentives are monetary rewards given for performing a certain behavior. These come in many different varieties; for example, they may be guaranteed vs lottery-based, or group-oriented vs individually-assigned.
Environmental restructuring refers to modifying the physical environment around someone in order to influence their behavior.
On the less intensive end, this could be as simple as having someone leave a pill bottle in a more obvious location or switch to using a pillbox with compartments for each day. More complex examples include carpooling potential voters to election sites to improve turnout, redesigning a workplace cafeteria layout to bias toward healthier foods, or setting up booths for influenze vaccination in offices or shopping malls.
Social support refers to the perception or reality that other people will provide assistance in a given context. It is a key component of several behavior models and plays an important role in mediating behavior change.
Identity priming refers to attempting to influence someone's behavior by emphasizing their being part of to a certain group or being a certain type of person. These often leverage social norms—particularly injunctive norms—and introjected regulation.
For example, voter turnout campaigns often emphasize the person's membership to the community or previous voting history in reminder letters.
Personalization refers to taking specific data from the individual in a behavioral intervention into account in offering a different experience vs. that given to others.
An experience may be personalized based on demographic data, psychographic data, behavioral performance, or other factors.
