The lying bent-knee oblique twist is an isolation exercise which builds muscle and strength in the obliques which are located on both sides of the rectus abdominis (Abdominals). These muscles help us to rotate and bend the torso, so it’s important that we have sufficient core strength to perform these movements.

Now, to train the obliques effectively, it’s best to use movements which involve trunk rotation. So, the lying bent-knee oblique twist is ideal for stimulating these core muscles and you can even add additional weight to increase the difficulty for even more results.
