Sit with your knees bent, heels resting on the floor.
Lean back so your torso is at at least a 45Â° angle, so that your abs become engaged. Arch your chest up towards the ceiling to flatten your back and straighten your spine. Slowly lift your heels off the ground and balance on your tailbone.
Hold your arms out completely straight in front of your chest and twist at your torso, rotating your shoulders as far left and right as you can. Turning from left to right is one repetition.
The Russian Twist is an excellent core exercise that targets the abdominals, obliques and lower back through a twisting motion, making it an excellent strength training tool for boxers, golfers, baseball players, or anyone looking to get 6 pack abs and a rock solid core. This Level 2 version increases the demand on the abdominal muscles and the obliques. You should be able to complete the Level 1 easily before attempting this version.
