Before wind tunnels I've seen some really basic aero testing which involves sticking bits of ribbon to you and just riding on the turbo in front of a massive fan. Probably some videos still on YouTube if we've got nothing better to do for the next couple of months? Or you can just practice making your frontal profile as small as possible in the mirror. It's how Chris Boardman started and he got quite fast.
