I was waiting patiently for the mechanic to replace some parts on my car when the old foreman motioned to me into his office. He pulled out a slanted wooden contraption from under his desk and asked me to stand on it. I almost toppled over. I couldn't bend my feet and ankles to match that 45° angle even if my life depended on it. I got off as quickly as I got on. He laughed and showed me how he could do it. Wow! And he's more than 60, a grand-dad, works like a horse and goes fishing weekends. Now, that's being healthy!!
He told me he learned about this contraption from a Taiwanese friend. It's supposed to help loosen the tendons behind the legs and strengthen those muscles and the spine and at the same time improves blood circulation, or something like that.... I wasn't paying too much attention anyway as he rambled on. I was figuring out where I could lay my hands on some planks and make one unit myself. And I did just that when I got home later. If one old grand-dad could do it, I could do it too.
I built mine with slightly less incline with the intention of adding on more height to increase the incline to the standard 45° later when I can handle the easier slope.
That was more than a month ago. Now I can stand on it and read the papers comfortably for 15 minutes without wincing. And I can also get up from a squatting position without having to straighten slowly for fear of breaking my backbones. That's no play-play guys, that's something good for your health. Wanna try?
