This myofascial massage therapy roller is a great way to increase flexibility and speed up post-workout recovery through trigger-point therapy or self massage. The GoFit 18" Go Roller is a great tool to awaken tired muscles pre-workout and to help knead aching muscles post-workout. Medium density foam over the UltraFin Core prevents flexing and breaking of the inner core and can hold up to 50% more weight than traditional “hollow” foam rollers. Target and roll out your back, lats, hamstrings, IT bands, glutes, quads, and more while improving blood circulation throughout your skin, fascia, muscles, and even tendons and ligaments! Dimensions: 18 inches long x 5 1/2 inches in diameter
