Question: What is the height of the D-shaped roller, from the 6" flat bottom surface to the top of the semicircle?
Document: roller price was good. shipping was a bit high. Don't know if I would re-order frm this company due to this.
This will do the exact same thing as the foam roller you can buy from your local sporting goods store BUT!!! this one is about 1/8 the price.
The roller is exactly what I wanted. I fractured my foot and use the roller when I do my physical therapy exercises to strengthen my ankle.
I use this to stabilize my neck when exercising in a sitting position so my neck is not leaning back. We just took a trip to Maui, Hawaii, and I used the flat side as a back support as my vertebrae go out and that kept me sitting straight. I also use it at home when watching tv.
this half round roller is very firm but it is supposed to be for what i need it for. my IT band is tight and the entire right side of my leg has hurt for years. somebody told me about this and i prayed it would work. lets me be clear, it hurts a lot, but it works. find youtube videos on what kind of stretches to do.
I bought these "high density" foam rollers for my personal training classes I do with "older" clients. Having them step from roller to roller to work on balance. I mostly put 2 together, making it easier. Within 3 days, the black particles that make up the rollers were crumbling!! They were already falling apart, and the my 1st week of use with these "high density" rollers was a disappointment.
We love these foam rollers - both the half-round ones (for flexibility exercises) and the full round ones (for foam rolling, self-myofascial release, etc). They're way cheaper than the competing brands out there, and the quality seems to be just as good.No reason to spend $40+, just grab two of these for less and be happy!
This product was recommended by my PT. I am able to use it at my home and able to strengthen my back.
This product is simple and well made, but I think high density actually means super high density because there is no give at all to these rolls. If that's what you want, then more power to you.
These rollers do what they advertise, and indeed they are extra firm. I was slightly disappointed when I opened the package and found that these are not made of polyurethane foam like I had hoped. Instead, they are made from expanded bead polystyrene in a cylindrical shape. This is the same type of foam you find in electronics packaging (a.k.a. "styrafoam"), but this product is black instead of the typical white.
Answer: no
