Stuck Seat Post

[JJDT]

What is the best way to get a stuck seat post out?

Wanted to do a setup and while in the setup it was found that my seat height was a bit to low. Wanted to adjust it and found it will not move stuck inside the frame. Bike is with LBS for two days now and when I asked this afternoon, I was informed that there was not any progress to get it out. Normal Aluminum Frame bike with Aluminum seat post.

So and I want to take my bike and with advise from this forum I might just get the seat post out myself.

Any tips and tricks for getting the seat post out of the frame.

Probably not helpful but this shows me it can get much tight!

 I have read of people putting the seat post ITSELF in a vice (remove seat), then using the FRAME to carefully wiggle/jiggle the seat post out, since great variety of hand positions and/or better leverage (done carefully…)…

Turn frame upside-down and over a few days spray penetrative oil into the seat tube through a bottle cage hole or at the BB let it soak then clamp the seatpost in a vice then pour boiling water over the frame at the seat/top tube lug while twisting the frame small gentle movements side to side.
