Quick and dirty way. Loop a chain around the pipe. Use a pair of vise grips to keep the chain from sliding. Hook chain to pickup or something straight out in line with the trap pipe. Remove most of the slack. Then stand or jump up and down on the chain.
Make sure the chain is straight with the rod with your weight on it. Usually after the first opening they work better.
