Although habit has demonstrated good predictive validity with PA, the experimental evidence for PA is limited ( Gardner, 2015 ; Rebar et al., 2016 ). Systematic reviews have not identified any randomized controlled trials (RCTs) that applied habit

It reveals the necessity to alter people’s barriers to induce healthy changes in their behavior. The main limitations of the present study
