You even sit in the one place for a period of time and then suddenly jump up, you can feel a bit dizzy. Is all normal. Plus you were working out. Even if I do the garden, I will feel the same way as you did for a while after finishing. Like moving a lot, putting a lot of effort into something. Then suddenly stopping. It happens. Not something I would be worried about.
