Crunches are an ab exercise I wish people would retire. They aren’t that effective and can actually do more harm than good, especially if you’re dealing with lower-back pain.
The 11 exercises ahead are great options if getting down on the floor is a hassle, you’d just rather not deal with the germs on the mat, or you’re in need of new moves for your core routine.
Don’t do all these moves at once unless you want to be extremely sore the following day. Instead, choose four to six exercises and add them into your workout, or do them alone for a quick ab blast.
