This instructional guide demonstrates how to use a tennis ball to relieve discomfort in the lower back, glutes, and feet. The layout identifies target areas such as the lower back for alleviating sciatica and back pain, the glutes for releasing tight muscles, the feet arch for addressing plantar fasciitis, and the heel to ease tension. A four-step visual sequence at the bottom shows the correct technique for placement, applying gentle pressure, rolling slowly, and completing a post-exercise stretch.
