Here´s one of the most popular fitness tests. Lie prone on floor and do as many
push ups as possible without pausing.
Males: Put toes on floor, keep body straight in a line and place hands slightly wider than shoulders. With every rep move torso down until chest stops just above floor. Return until arms are fully extended. Repeat.
Females: Put knees on floor with feet slightly up, keep body straight and place hands slightly wider than shoulders. Move torso down until elbows are flexed right-angled. Return until arms are fully extended. Repeat.
