YES IT IS !!! .....
I can write that using it on a daily basis, with caution and intelligence doing long sessions no more than 1 hour, with me it is a very effective tool re-washed, and I was not harmed, and no harm to healthy level for my legs. And 'normal to feel pain all'nizio when you are not used to.
It looked like a bullshit ....... But it is truly amazing how this tool can dissolve without last effort, and push past; not only stretching the muscles of the legs, but even to open, widen more unlocking the hip joints (hearing popping). In fact, come very slowly to the full maximum opening, finally reached after 20 days of training on this tool, and continuing to train then adding shims, are able to raggiure even the opening of 200 degrees, and always refer sitting on the maximum opening after another 10 days I HAVE ACQUIRED A remarkable opening JOINT JOINT mOBILITY OF EVEN THAT I HAD BEFORE, AND MY MUSCLES HAD SO LOOSE I could PULL FOOTBALL VERY VERY HIGH THAT BEFORE I could not for.
I can not speak ill of the leg stretcher. Unlike those who do not have known how to use intelligently.
