Low back hurt? Trigger point massage ball/ foam roller from the middle of your butt crack, & move it/ circle it around. If the massage ball/ roller is too hard and painful you can either put a little blanket between you and the device, or you can remove the ball all together and just roll up a little blanket or towel. You can make it as big/ thick/ width you want, whatever is the most comfortable for you. It should be uncomfortable or hurts so good tenderness or even just pressure but should not get above 3/10 pain with this activity. If you do Make the roll smaller/ softer don’t give up on it. I promise once you get the right size and comfort level and you are consistent with it you’ll be thanking me! 🤗
