Imagine a vertical line that runs through the body, neatly dividing it into halves. Any movement you make parallel with this line is done in the sagittal plane. Now consider the movements you make during your workouts and how many of them are parallel to this line. It’s probably most of them – from classic bodyweight moves like lunges and squats to free weight exercises like presses and curls. Then, when you do mix it up, the chances are you’ll start moving laterally, with side lunges or skater jumps. These are movements done in the frontal plane.

All of these are excellent exercises that will do you a world of good, but they do not prepare your body for another kind of movement you do regularly, especially if you play a lot of sport – twisting. Consider another imaginary line that cuts your body in half at the waist. Movements where you twist your upper or lower body parallel to this line are said to be done in the transverse plane, and the chances are you don’t do so many of them during your workouts.

Rectify that by doing the Russian twist, which works in the transverse plane and strengthens muscles that you might be missing with your straight-up-and-down crunches and sit-ups, such as the obliques. Regular Russian twisting can also help improve your posture and if you’re about to take up kayaking or canoeing with a vengeance, there is no better core exercise to prepare for life with a paddle.

How To Do The Russian Twist

  1. Start by sitting on the floor, with your knees bent and feet flat on the ground.
  2. Then lean back so your upper body is at a 45-degree angle to the floor. Keep your back straight at this angle throughout the exercise, as it will be tempting to hunch your shoulders forward.
  3. Link your hands together in front of your chest, then brace your core and raise your legs up off the ground.
  4. Rotate your arms all the way over to one side, then do the same in the other direction. Count that as one rep and aim for 20 in total, or set a timer for a minute and keep twisting till the beep goes off.

If Russian twists are proving too severe a challenge, then you can make it easier on yourself by not lifting your legs off the floor during the exercise. To make it harder, add in some weight by holding a dumbbell in each hand as you twist.

When the weighted twist gets too easy, you can turn to an exercise ball. Lean your upper back on the ball, bend your knees at 90-degrees and plant your feet on the floor. Then twist away, making sure you keep your back straight. Trying to avoid toppling off the ball will make everything all the harder.
