When I used your product, Armwalker, to walk on two legs, it was unnatural to walk by four-legged walking instead of two-legged because I wasn't familiar to it at first,
but now I'm doing well because I'm used to it.
Walking along with shoulder and arm exercises, the muscles in the arms that have not been used in the past are also strengthened, which is very helpful to my health.
I will recommend my friends and acquaintances to use the product for their health improvement. And I will promote it as well.
