4KOR Massage Balls for Trigger Point Therapy - Myofascial Release Ball - Muscle Relief for Back, Neck, Shoulder, Foot Pain - Fitness Massage Balls for Mobility - Deep Tissue Release Ball

I bought this set after buying the mid sized one from another company and loving how much more release is achieved by its design over the smooth type which is what i have been use to for many years now. I wanted to try the next size up, the red one here, knowing it was likely to deliver even more relief. I tried to shop with the same company but their set was unavailable as most of their stuff was so, I found these.I love this jagged design. I just wish I hadn't waited so long to try them! It EFFECTIVELY breaks down the tension, offering relief into the next day when you are persistent in using these. You can easily travel with them as they come in a handy bag. Functional, effective, durable, great quality product seems like it will last a lifetime.

After using my friends I had to buy one for myself. I love the gym so I’m always sore. This is amazing for quads, glutes lower back relief.

Awesome for back pain. I travel with the smaller ball inside a pillow case to use for trigger point muscle release while traveling. Especially if I’m stuck in an airport I do not travel without it.

I am an avid cyclist, and I was in the gym doing leg curls and felt something tighten up. The next day it was hard to walk. Got some relief from rest, and a visit to the chiropractor, but was still in pain and could not ride out of the saddle. Read an article about hip flexor strain which led me to this massage ball.Saw a similar product that was a little smaller, but delivery date was much longer so I went with this one. Glad I did. Size was perfect for me. I followed directions and I could feel the ball loosen the knot in my muscles. Noticeable improvement immediately, and it got better with continued use.Using it as a self massage tool it works well on quads and hamstrings. It is more difficult to perform a self massage on calfs. A roller would be easier to use on all three muscle groups, but I prefer the ball to a roller for soles of feet and as for hip flexor muscles a roller is useless but the ball is on the mark.Would I buy it again? Unless the dog steals it and buries it in the yard, or your kid uses it for field hockey this one should last a lifetime. A little expensive for a hard rubber ball, but I am not complaining. Cheaper that a professional massage, or a visit to the chiropractor with equal or better results.

These work amazingly for sore muscles!

So, I bought the 4KOR Fireball a year ago (June 2022). After I got it, I didn't start using it at all. It just sat around.In my use case scenario, I am a side sleeper and whenever I don't use my knee pillow to prop in-between my legs, my spine is not straight and aligned and so I have lower back pain the next day. I don't always like using the knee pillow despite it being TOTALLY EFFECTIVE because I'm not used to having a pillow in-between my legs when I sleep and it seems to keep me up longer and also prematurely waking me up in the middle of the night sometimes. But NO DOUBT, the knee pillow DOES WORK for me when I decide to use it.So, fast forward to 2023, I started using the 4KOR Fireball a few months ago for the first time. What I do is lay out my yoga mat, place the 4KOR Fireball on the yoga mat (SEE PICTURES), and then I carefully lay back where the 4KOR Fireball is rolling / rotating and massaging across my entire lower back area and I switch the Fireball to work on both hips areas where I also have pain.MAN! LET ME TELL YOU! THIS FIREBALL REALLY, REALLY WORKS!!! It massages the lower back and hips. YEP, there's PAIN, but that's the Fireball working out the tenseness I am feeling, thus the pain. After that, I feel pain relief. Typically, I will use the ball before going to bed if I don't wanna use my knee pillow. Sometimes, I may use it after I get up. Either way, it's VERY EFFECTIVE!Now, besides the knee pillow, this is another way to work out and relive lower back and hip pain for myself. This was definitely worth the money. The only regret was using it 8 months after I bought it and not using it SOONER for therapy tension pain relief.The 4KOR Fireball is a very hard rubber with no give at all. You can't squeeze it or anything like that. It has ridges on the ball (SEE PICTURES). It's a solid ball at 3.2 inches in diameter and should last indefinitely.HIGHLY , HIGHLY RECOMMENED! :-)
