Domains	Constructs	Strategies
Intervention characteristics	Evidence strength and quality	B2L intervention resources and evidence from two pilot studies.
	Adaptability	Flexible intervention delivery model (ie, during class-time, breaks, before or after school) requiring minimal access to facilities (ie, can be done in the classroom) and equipment (ie, body weight exercises).
	Complexity	Time efficient, student-directed intervention requiring only two or three 10 min sessions per week.
