Two movements to train abdominal muscles
1. Crunch your abdominals and lie flat on your back. Hold your head with your hands and bend your legs at the knees. Raise your hands flat in front of you, and at the same time curl your abdomen to lift your upper body. It is advisable to reach your hands above your knees. Hold for about 2 seconds and then return to the starting position.
2. Lie flat on your back with your abdominals curled up and your legs raised. Hold your left knee with both hands and straighten your right leg. Lift your upper body with abdominal curls and raise your right leg at the same time. Keep the position of your legs unchanged and your arms straight. Hold for about 2 seconds and then return to the starting position. 4 sets x 20 times each.
