Oblique Sit-up
To strengthen your sides and improve your rotation and core strength.
Lie on the floor with your knees bent and feet flat on the floor. Put your right ankle over your left knee, your left hand behind your head and your right hand on your sternum. Twist your left side and try to bring your elbow as close to your knee as you can.
Make sure you are doing a full range of movement, i.e. putting your elbow back to the floor before the next rep, and swap sides after your set number of reps.
