How To Do The Torso Twist Exercise Properly

Torso twist also known as oblique twists exercise is a dynamic movement that activates your core and strengthens your abdominal muscles.

How to do a torso twist:

Required equipment: medicine ball (a mat is optional)

  • Sit down on the floor with your legs clamped together and bend your knees and hips to about ninety degrees. Place your medicine ball to the side of your hips.
  • Keep your feet firmly planted on the ground, if this position poses to be too easy for you to hold later in the exercise you could lift your feet off the ground slightly.
  • Ensure your chest stays upright and your back straight. Lean back until your body is at about a forty-five-degree angle from the ground.
  • Tense up your core and make sure that your chin remains tucked throughout the exercise.
  • Lift the medicine ball off the ground and hold it in front of your body keeping your arms slightly bent. This is your starting position.
  • Slowly and in one controlled motion twist your upper body to the left moving your arms along with your body.
  • Rotate as far as you can and touch the medicine ball to the ground
  • Rotate back to your starting position then to the right keeping your lower body as still as you can.
  • Repeat this for fifteen reps in a set of three, taking a thirty-second break in-between each set.


Remember to breathe steadily and deeply throughout the exercise because holding your breath may cause fluctuations in your blood pressure.

If you are struggling with stability cross your lower legs to make it easier for you.


Torso twist primarily works your obliques, rectus and transverse abdominis which are your core muscles and the muscles on the side of your torso.

Your hip flexors and erector spinae are also worked but with much less strain placed on them. These are the muscles at your hips and lower back.



The workout targets the obliques and core this causes them to break down and burn extra calories apart from those you burn doing the workout.

This causes your body to break down the fat around the targeted areas to be able to provide this energy.


Torso twist works out your entire core, including your sides and back muscles.

So as your core gets stronger, the muscles attached to your spine get stronger, which will help you keep yourself upright with better posture.

This also reduces the occurrence of back pain that arises from slouching over for prolonged hours.


Your core is the powerhouse of most of your movements so strengthening your abdominal muscles can boost and make you more proficient in performing athletic movements.

Such as jumping for a rebound in basketball, throwing a punch or swinging a tennis racket. You will be able to do all this with more power than you would have been able to do initially.
