Description:The man pictured here from a lower-left anterior-oblique view, was inside a gymnasium performing various strength-training exercises. At this point in his exercise routine, he was performing leg extensions on a Pulse® Leg Extension machine. His legs were fully extended, with his ankles cradling the cushioned, moveable and weighted segment of the machine. The legs are slowly brought up to the fully-extended position, and held there for a few seconds, then slowly allowed to return to the flexed position, with the lower legs draped over the edge of the seat when finished with each repetition of the exercise (see PHIL 14128). Hopefully, he was also keeping well hydrated during his exercise regimen by drinking fresh water during his workout.
