Get Jessica Ennis' body
OK, so maybe us non-professional athletes are a long way off having Jessica Ennis' body, but if you practise these exercises put together by the experts at Fitness First, you'll be a little step closer.
All you need is a medicine ball and a little will power.
Do 10-15 reps of the following exercises...
Sit on the floor with your knees bent and feet flat. Hold the medicine ball extended out in front of you, and recline back so that your body is angled about 45 degrees. Keeping your lower body still, twist your body right then left.
Lie on your back and bring your hips up to 90 degrees. Place a medicine ball in between your knees and put your hands out to the sides. Slowly lower both knees to one side. When you get close to the ground, hold for a second and then reverse directions.
Start in the same position as above. Exhale and slowly lower your feet towards the floor. Keep your abs engaged so that your lower back remains stable. When your feet are just above the floor, hold and then slowly return to the starting position.
Have your back facing a wall, feet shoulder-width apart, and hold the medicine ball near one hip. Rotate your body while driving the ball diagonally across you, finishing on the opposite side (but overhead) to where you started. Think about throwing the ball from a waist height position across the body to an overhead position. Inhale on the way down, exhale on the way up. Repeat on the other side.
And there you have it - the makings of an ab-fab bod' just like Jess!
