This is a massage tool designed to pinpoint and release the deep muscles in your abdomen, specifically the psoas and iliacus muscles. It has a similar shape to the famous "Pso-Rite" and effectively stimulates muscles deep within the body that hands and foam rollers can't reach. 【Get the effect of one chiropractic session for 1,800 yen!】 Even if you don't have time to go to a chiropractor, using this tool for just a few minutes before bed at home will make your lower back and hip joints feel surprisingly lighter. 【"Absolutely" recommended for these concerns】 ・Feeling a tightness in your hip joints from long hours of desk work ・Having "swayback" and feeling your lower back lift or hurt when lying on your back ・Finding foam rollers insufficient for stimulation ・Feeling like you want a deeper massage even when going to a massage therapist 【How to use】 It's easy to use. Simply place the tool on the floor and lie face down on the protrusions. Your own weight will sink you in, powerfully releasing the stiff muscles around your lower back. You can also use it on your back (between your shoulder blades) and the back of your thighs. 【Product Specifications】 ・Size: Approximately 28cm ・Color: Black ・Material: Hard plastic (strong enough not to deform under weight) ・Condition: Beautiful condition, used only a few times. 【Shipping】 Shipping costs (750 yen~) will be considerable due to the bulky nature of the product, but the price includes shipping. #PsoasMuscle #IliacusMuscle #PelvicCorrection #PelvicRelease #Swayback #LowerBackPainRelief #TriggerPoints #FasciaRelease #Acupressure #BackMassager
