Shaping in behavior modification is best defined as designing a new behavior chain using rewards because it involves reinforcing successive approximations of a target behavior. In this context, shaping is a gradual process where small, incremental changes lead to the desired behavior. By rewarding each step toward the final behavior, individuals can learn and maintain new skills effectively.

The process emphasizes the importance of reinforcing behaviors that are closer to the desired action, helping to build a chain of behaviors leading to the final goal. This technique is particularly useful in personal training and coaching, where clients may need encouragement and support to develop complex skills or achieve fitness goals over time. Each successful attempt is celebrated to motivate continued progress, making rewards integral to the shaping process. This approach combines the concepts of reinforcement and progressive milestones, fostering a more effective behavior modification strategy.
