See the picture & short amount of information below. We've used the inner tube during practice as a resistance band, for our core, shoulders, forearm and wrist. I have tied quite a few of them on the fence. We'll use them more often in the future, but they are there for anyone to use when waiting during drills. We've also done the crab walk outside, but more inside. We'll do that as part of a Indoor routine, and you can do any one of these on your own.
I have a bag of tire inner tubes, and I will surely give you one if you desire. You can take it home and tie it wherever and do 3 sets of 10. Do it slow forward, hold, and slow back. See below the recommended way to do one exercise with the inner tube tied to the net post. I'll show you one for your shoulder, with the inner tube tied to the fence.
