Curl-up was created in 1951.
Koalas do smetimes curl up tightly when they sleep. They curl up in winter to keep warm.
Partial curl-ups are a core strengthening exercise that primarily targets the abdominal muscles. During the exercise, an individual lies on their back with knees bent and feet flat on the floor, then lifts their upper body towards the knees while keeping the lower back pressed to the ground. This movement engages the abdominal muscles without requiring a full sit-up motion, making it a safer option for many people. Partial curl-ups are often used in fitness assessments and training programs to improve core stability and strength.
