I'm currently doing the 12 weeks challenge, and I realised last week that my gym doesn't have any boxes, nor stools :/ I know it sounds kind of weird, but I guess Japanese gyms don't really prioritize these kinds of settings...
There are mats, and I have tried doing my jumps by piling mats up against a wall, but even then the pile is shaky at best, and I don't have enough mats available to go very high (most mats are used for classes in the building, such as yoga, stretching, etc.).
My question is: is there an alternative to box jumps?
Thanks in advance for your help!
