RESET-CKD is evaluating an intervention to support Black adults with chronic kidney disease (CKD) to reduce their sedentary (e.g., sitting) time. Half of the participants will be randomized to the intervention, where the goal is to support individuals to reduce their sitting time, and the other half will be randomized to an attention control condition that provides CKD-related education not related to sedentary behavior. All participants will be followed for 12 weeks.
