Firstly, if you don't know how to bunnyhop a bike with a freewheel, learn how.

Then and only then try doing it fixed.

Lift front wheel, stop pedaling while twisting bars forward. Makes the rear wheel pop right up. Lower gears help for figuring it out, but eventually you'll be able to hop your giant track bike gear just fine. It's all technique, not muscle, and when done right isn't hard on your wheels.
