This test begins with students' chins above the pull-up bar and their arms flexed in a pulled up position. A chair may be used to enable the students to begin in that position. The teacher keeps track of the time while the students hold their chins above the bar. The time stops when their chins drops below the bar. Abdominal strength is measured uusing the curl-up test.
Students lie down on their backs.
Their legs are bent at the knees. The students cross their arms over their chest and place their hands on opposite shoulders. This isolates the usage of abdominal muscles. The students work in pairs. One stablalizes the other feet.
