Okay, so I've got this big loft apartment that has a lot of wide open space and is just begging to be used.... so I was wondering...
Even though it has concrete floors... i want to do some rolls on it.
.... can anyone see any potential problems?
If you really want to roll outside the dojo, I'd consider investing in some folding mats. You might not hurt yourself doing seated rolls or rolls from a kneeling position. But you what if you just keep upping the ante, going to standing rolls, then moving up to jumping rolls. A back or neck injury just isn't worth taking the chance!
EVERY aikido student wonders if they'll be able to take a roll or fall on concrete. They want to know if what they are learning is real. I know I once wondered this too, but following the advice/urging of my sensei, I finally came to the conclusion that I'd just wait for the day when I really had to take a fall. And I've fallen a few times outside the dojo, not from being thrown, but just from my own clumsiness. I rolled just fine each time.
The abuse your body takes from years of ukemi can have a cumulative effect. This might not apply to everybody, but I sure feel my 15 years of ukemi from time to time. So, take it slow and just ramp up the ukemi gradually, you'll thank yourself for it later in life!
There used to be two students who were extremely gun-ho in our dojo. They turned a garage into a mini dojo, where they could practice on their own & as often as they liked. The instructors at the dojo tried to discourage them from doing this, but they just went ahead with this anyway. They started out slow, then ramped up to full on throws on each other. They had made make-shift mats with foam strips & carpeting. On day one of them was thrown and he landed in an unpadded spot on the floor. He severely injured his back, which required surgery. He has never been back to our dojo. Just food for thought!
Best wishes on your training!
