Here is a quick plank series you can do at home or at the gym. Planks are great because they activate almost all the muscles of the body. The main area I like to tell my clients to focus on during their plank is their belly button. I tell them to pull it in towards their spine and up towards their ribs. This usually helps to provide a little more length in the lower back and activate all the underlying muscles of the stomach. The rectus abdominis/6 pack/vanity muscles are great for swim suit season but it’s the transverse abdominis and internal and external obliques we want to strengthen to help with lower back pain.
