Exertion

Man lifting

Exertion is the physical or perceived use of energy.[1] Exertion traditionally connotes a strenuous or costly effort, resulting in generation of force, initiation of motion,[1] or in the performance of work.[2] It often relates to muscular activity and can be quantified, empirically and by measurable metabolic response.
