Lateral flexion is another common way we see the core trained – this occurs in exercises like side bends or side crunches and typically targets the obliques. However, you can also train the obliques by resisting lateral flexion. This can be done by performing single arm suitcase carries or even single arm presses and/or rows that place a load on one side of the body at a time. If you need to get more bang-for-your-buck out of pressing movements, try using single arm bench or shoulder press variations for more core work!
