What are some conditioning excersizes for small spaces

Alright so im trying to get my horse ready for camp in a few months but at my house I only have a 30 ft diameter round pen to work her in, and not a ton of training supplies. I asked this before but everyone said "ride more, get someone to ride her for you" but the problem is not time, its space, so even if someone else worked on her they wouldnt have the space either. So im looking for ways to condition her from the ground, something a bit different from lunging

You got those answers because those are pretty much your only options to get a horse fit. a 30 foot round pen is basicly big enough to do most things you would in an arena (aside from large patterns and jumping).

There isn't a quick fix. Ride regularly, spend lots of time trotting. Go up hills. Lounge... Lounging is kind of boring, but trust me your horse wont care unless you do it excessivly. If you don't have a lot of space to work with I am assuming your horse is turned out in a small area (if she isn't then I would suggest working with her in the turn out field). If she is turned out in a small paddock then you need to lounge or ride her regularly so that she can burn some energy and stay fit. It isn't fair to keep your horse in a small area then never let it get its energy out.

You need to just tough out the lounging thing if you are determined to get her fit without riding.

There really isnt that much you can do from the ground other than lounging... Maybe try some ground driving with your horse, this wont really do much for her fitness though, as it would be the same thing as you leading her around... but it will help with control and training (for control and training, also try teaching your horse some showmanship) Ground driving with out a large area isn't very effective.
