You need a heavy, solid bench to hold the work. That's the key to using
hand tools effectively. Trying to saw, chisel, or especially hand plane a
board that's sliding, shaking, or vibrating is a nightmare.
If the board has lots of cup or twist, then the first step is a using a "scrub"
plane or perhaps even an adze to hog off the high spots and get it roughly
flat. This step goes pretty quickly...

If you don't need to scrub (and I recommend your first try be a fairly flat
piece), then use the normal #5 bench plane and finish with the #7 or #8...

The two fellows above are masters and make it look easy. Their planes
are well-tuned and sharp. They have solid, massive benches which helps
a LOT. So you'll sweat more than these guys the first time you try. But
it's a quite and relaxing process.
