These abdominal exercises from physiotherapist Nick Sinfield strengthen your core muscles, the muscles around your trunk.
Before you begin, warm up with a 6-minute warm-up routine. Afterwards, cool down with a 5-minute stretch.
Target: abdominal muscles
ie on your back, knees bent and feet flat on the floor, hip-width apart. Place your hands on your thighs, across your chest or behind your ears. Slowly curl up towards your knees until your shoulders are about three inches off the floor. Hold the position for a few seconds and lower down slowly. Perform 12 stomach crunches.
