So, tell us, niemiro, do you train at home?
lol. As much as I can! I have been trying to pursuade my parents to allow me to build something like that for *years*. So far they have been extremely reluctant to start drilling large holes in the wall.
But I have tried and tried! I have repeatedly made small computer models to show and test various designs and compromises. My personal favourite is in the stairwell, but it is a huge overhang which comes back over your head. I have spent long hours designing the structure and calculating strenths and strains. I have also been working at getting a larger wall in the garage instead.
But no luck so far! However, I do have a chin-up bar, I climb trees in the garden (we have a bank of ~120 year old trees, which are extremely tall and great for climbing or practicing ropework), and I go to the local climbing centre far too many time a week (amazingly, I live ~30 minutes away from one of the best climbing centres in the UK)
Maybe one day!
