Wanted: 20kg weight

Preferably one or two weight plates with a hole in the centre, or a kettle bell wanted- thinking £20ish.

What have you got?

you can have my stomach, and your welcome to it, bloody thing.

I've lost about 2kg of my own weight last month - if you find it, you can keep it. Hope that helps.

Two bags of spuds? Borrow one from a local gym? Wheel bike to local gym and use it there?

My intention was:

• Put bike in turbo
  
• Hang weight from pedal axle
  
• Rotate rear wheel backwards, raising weight until crank is parallel with ground/zero offset figure is highest
  
• Record zero offset figure displayed on PC-V
  
• Put numbers into spreadsheet to calculate slope
  
• Enter slope into PC-V
  
  

So easiest to do at home I think, and 20kg is a lot of spuds!

20kg bag of sand from B&Q?

I've got a 20kg bag of Mapei tile cement, not the easiest of things to hang from a pedal however.

I improvised:
