The machine leg raise crunch is an isolation exercise used for building muscle and strength in the abdominal muscles of the core. But the obliques also get worked secondarily. Now, using the ab machine can help you to develop a lot of core strength but you also want to do stabilization exercises for the core to ensure you have proper development.
You don’t want to use too much weight during this exercise as it can be more dangerous than effective. So, stick with a resistance load you can train with by using a full range of motion during each repetition. The machine leg raise crunch is a great addition to any core training routine.
