Infiniti Gravity Strider (Chalford Hill. GL6.)

Hi All, I have an Infiniti Gravity Strider / Exercise machine that a lovely person on here gave me a couple of months ago, the idea being that my wife could use it to improve her knees and I could use it for general fitness ; sadly, it's rather larger than we expected and as such it's sat in my shed, not being used, which is a bit daft. As such I'm rather hoping someone can use it rather better than I have. Collect from Chalford only please. The photo is a generic one as the original is rather hidden behind stuff !!
