A multiple-baseline across-subjects design was used to evaluate the effectiveness of a video-modeling intervention delivered on an iPod Touch to teach three high school students with autism spectrum disorders (ASD) or intellectual disability to complete workouts independently at the local community fitness center. Individualized workout routines including three strength-training machines and/or exercises were created for each participant. Exercises, weight used, and number of reps were selected with the guidance of fitness center trainers and staff. Data were collected on the percentage of total steps each participant was able to complete independently, without prompting, across baseline and intervention conditions. Findings indicated that the intervention was successful in increasing independent performance for all participants.
