As I get older, I find that I am sometimes stiff, sore, and not as flexible as I would like, especially in the morning and now that I work at a desk all day. I purchased this specifically for loosening joints and muscles, as well as to keep the lymph moving through my body. This plate is highly regarded as the only 'inexpensive' plate that truly does what it purports to. I use it every morning before getting on my rebounder & swinging the kettle bell and throughout the day, too. I love it! My shoulders & neck no longer hurt all day.
