You will need a foam roller for this. Personally, I am a fan of foam rollers that have a bit more ‘give’ to them, meaning they aren’t super hard or rigid. Oftentimes, when I am working with someone who has low back pain, I find a major contributor to that discomfort is coming from excess tension & overly active quad muscles (the muscles of your thigh). When there is excess activation of these muscles, they pull your pelvis forward which in turn (& through fascial connections), pulls the front of your low back forward.
