Product Description

The 321 STRONG solid core, medium density foam roller uses patented technology to deliver a therapeutic self massage comparable to a professional massage from a physical therapist. The 3 unique massage zones replicate the thumbs, fingers, and palms so you can get the exact massage you’re looking for. These 3 massage zones help to increase blood flow and circulation to problem areas, decreasing recovery time, and increasing mobility, flexibility, and range of motion.

Built to last, our solid core massage roller with EVA tread is made from top grade materials, and won’t lose its shape over time, even with daily use. Its lightweight materials make transport a breeze, and its compact design allows you to properly focus pressure on the affected areas.

Perfect addition to any workout routine

Your 321 STRONG foam roller heals damaged soft tissue, increasing flexibility and range of motion, while reducing pain and soreness. Its compact size allows you to target specific muscle groups and pain points. Increase blood flow and circulation to your muscles and soft tissue before and after workouts. Enjoy therapeutic benefits like decreased recovery time from injuries and increased mobility. See the same benefits as a deep tissue massage - smoothing knots, removing adhesions and trigger points. Beginners and athletes alike see the same relief from sore muscles, sciatica, plantar fasciitis, back pain, shin splints, and reduction in scar tissue.

4K eBook Included

Learn how to use your massage roller and target specific muscle groups by both reading AND watching the techniques being demonstrated.

Loaded with Features

Patented technology, sturdy construction, and high quality materials come together to deliver a massage roller with exceptional value. Allow the 3 unique massage zones to deliver a custom deep tissue massage to your problem areas. Designed specifically to address muscle soreness and joint stiffness. The 3 massage zones apply pressure in varying degrees of density, encouraging muscles to release stored lactic acid, kinks, and knots. Unlock the secret of sports therapists, in the privacy of your own home. Our 500 lb rating supports all body types while maintaining consistent resistance, allowing you to use your own body weight to control the massage intensity. Your 321 STRONG foam roller is easy to clean, and even easier to take with you on the go.

5 Stars
Great quality and very effective!
This is excellent quality and super durable. It still seems brand new after years of consistent use. I expected the foam to be spongier, but it's actually for the best that it's so firm because it's easier to control. Although the spikes look a bit intimidating, the surface feels surprisingly even when I'm rolling flat, and I can also target specific spots simply by adjusting my position. By turning my torso to the side while rolling my back, I can even work the knots under my shoulder blades, which is fantastic since that's mainly why I bought this.It's also proven quite effective at relieving tightness and cramps I often experience due to Restless Legs Syndrome. Rolling my calves and thighs before bed really relaxes my legs, which helps me fall asleep much faster and wake up without soreness. My best friend owns one too and swears by it after vigorous workouts. It can even be used purely for pleasure, as the massage function feels enjoyable all around.Best of all, there are plenty of ways to utilize it regardless of one's fitness level. I have poor upper body strength but still found many easy exercises that alleviate my back and leg issues. There are tons of great guides online. I suggest securing loose clothing and long hair beforehand, and I'd also recommend starting slow and taking care not to overdo it. This is an extremely versatile and valuable tool when used in moderation, but going too long or hard, especially on a single area, can result in bruising. Once I began limiting sessions to 15 minutes, I had no further issues.My only complaint is the length. I'm a woman with a small frame, and this is the same size as my upper back from shoulder to shoulder. I struggle to stay perfectly straight while rolling my back, so I start falling off the side as soon as I become crooked. With a few extra inches of leeway, I wouldn't have to stop and reposition so often. That's just a matter of convenience though. A longer model wouldn't be any more effective, and I don't plan on replacing this one until absolutely necessary because I'm so satisfied with it otherwise.
