321 STRONG Foam Roller – Medium-firmness massage roller. Targets deep muscles and relieves back pain (includes e-book with 4K instructional videos).

PATENTED TECHNOLOGY: Relieve sore muscles, perform deep tissue massage and acupressure with our medium density massage roller, great for relieving back pain. The patented projections extend deep into soft tissue and fascia to break up knots and calm tense muscles in your neck and back

SUPERIOR QUALITY: Our textured foam roller mimics the hands, fingers, and thumbs of a physical therapist, but in the privacy of your own home. It features a super-strong and lightweight core, and is entirely wrapped in BPA-free closed cell EVA foam for a premium look and feel. The density of the projections, and their unique shape and pattern offer effective results with a comfortable level or penetration into the soft tissue and muscle fascia

TARGETED RELIEF FROM PAINFUL ADHESIONS: Exceptionally suited for a comfortable yet effective deep tissue massage, our product is designed from the ground up to flush lactic acid from muscle tissue, enhance pre- and post- workout stretching and recovery. It is firm enough to offer therapy to the muscle groups on either side of the spine, yet soft enough to not hurt the spine when rolled directly

UP YOUR STRETCH GAME: Our massage roller offers three massage zones that allow you to dial in your massage intensity. The smallest projections are like a massage therapists finger tips, the larger projections mimic the thumbs, and the largest ones feel like the base of the palms. There is no hard plastic in our product, so you won’t crack it, and it supports an incredible amount of weight so it won’t deform or flex

QUICK AND EFFECTIVE: Foam rolling for just 20 minutes after exercise, and again at 24 and 48 hours has been clinically proven to reduce recovery time by 20%, increase flexibility by 10%, and reduce soreness by as much as 30%. They have also been shown to decrease the risk of injuries in the first place
