I purchased something called a Terra-Core at a thrift store. It appears to be a longer (kind of like a boat shape?) version of those big balance things (blanking out on the name of them, but flat on one side and rounded on the other) that I've read about some of you owning and liking. I'd also read that some of you use those for the balance parts of LMR instead of the smaller balance discs. Is anybody familiar with the Terra-Core, and do you think I could use it the same way? It has handles for push-ups (flat side), which aren't the right distance for my arm length. It also says that when the rounded side (inflated side is up) that it can be used to reduce impact for jumps and things like that, but I am not confident enough in my balance to try that yet. lol I'm not really sure why I bought it - it was cheap and I kind of have an addiction to workout equipment, but I honestly didn't have a plan in mind when I bought it as for what to use it for. Wondered if anyone has used one and if they liked it enough to keep it or if I am just cluttering up my exercise room with something that won't be very useful.
