Means, standard deviations, and correlations among study variables.

Variable	M	SD	1	2	3	4
1. AI-Contextualized self-efficacy	3.24	0.82	1
2. Exercise self-efficacy	3.50	0.53	0.470***	1
3. Exercise outcome expectations	3.35	0.55	0.495***	0.435***	1
4. Exercise engagement	3.43	0.50	0.435***	0.381***	0.413***	1

N = 2,279. M = mean; SD = standard deviation; AI = artificial intelligence. Pearson correlations between mean composite scores are reported. The correlations were not adjusted for gender, age, or grade. All significance tests were two-tailed. ***p < 0.001.
