7 Exercises That You Don't Ever Want To Do
Double Leg Raises

Double Leg Raises are done by suspending yourself as you hang onto a bar and raising both of your legs up. It’s said to be a core strengthener but in fact, is ineffective.
Not only that but if the exercise isn’t done properly, you can overwork your hip flexors. This can cause spasms in the hip flexors along with the risk of a herniated disc. This exercise causes the weight of your legs to put a lot of pressure on your spine and vertebrae.
