If leg raises are bad for your lower back, there are ways to fix them. Or, you could replace them with the double deadbug instead — a bodyweight abs exercise that helps strengthen your deep core muscles without weights and can easily replace or join leg raises in your workout line-up, depending on your preference.
Thankfully, there’s a multitude of exercises you can do to build a stronger core and, while as a trainer, I typically prioritize big lifts and compound exercises in workout programs, abs exercises are effective and they certainly have a place.
