2. Lean against a tennis ball.

Steps to take:

Put a tennis ball under one of your buttocks while you sit down on the ground. Roll your body gently forward and backward on the ball until you can feel the source of the pain. Bend the knee of the same leg while keeping the ball in this location, then place your foot on the other knee. To keep your balance, put your hands on the ground behind you. After one to two minutes of resting in this position, turn sides.

How it works: Massaging your glutes with a tennis ball relieves tension and increases blood flow to your lower back.
