In Mulan the training montage involved running through a field while being shot at by Arrows on Fire.
In Mulan II, it is averted by Mulan, who begins teaching the girls to fight by telling them that one should be gentle and kind to others, in a reverse the scene with Shang from the first part of the film.
In Star Wars, Yoda forces Luke to perform inhuman feats of strength, dexterity and stamina as part of his Jedi training. (The novelization/written version of the stories mentions he had to do a thumbstand, i.e. a handstand on one thumb.) The implication, however, is that Luke is being forced to rely on the Force — Yoda is making him perform superhuman feats that, as a human, he is not capable of performing — but as a Jedi, with the Force flowing through him, he is.
Sith lords usually got Training from Hell, in order to make them desperate and angry enough to turn to The Dark Side. Several ended their training by killing their masters.
After Bane sets up the Rule of Two, the only way for a Sith to graduate is to kill their master.
Soldier: All of first-generation soldiers were picked as infants and then put into regular military training, probably since they were able to comprehend orders. There is a flash-back later on, where 8 years old Todd pulls No-Holds-Barred Beatdown on one member of his future squad, and just after this, he sit back to his exam, calmly continuing it. It's the age of those kids what made the Training Montage at the beginning so disturbing.
Kung Fu Panda: Po gets abused by a dummy that knocks out a tooth, gets ensnared and cooked by the training devices ("There is now a level zero"), and gets beat on by four of the Furious Five and Master Shifu. (Although it could have been worse — if Shifu had had Tigress face Po, she would have probably killed him).
This is actually a subversion at first. Shifu doesn't want Po to actually complete the training, he wants Po to give up and go home. After Po refuses to give up and Shifu changes his mind, the training gets less hellish but still rather difficult.
Let's not forget Kung Fu Panda 2 which reveals that Tigress punched ironwood trees for TWENTY YEARS and now feels absolutely nothing on her whole body. Keep in mind she doesn't just not feel pain, but ANYTHING. Would really suck if she wanted to get a massage, or if she and Po got together. There's also Tai Lung who was pushed by Shifu to train until his bones cracked. Ouch.
It should be noted that this is Truth in Television. Serious practitioners of kung fu really do train that hard.
The main character in Wanted goes through all kinds of physical abuse as he is trained by the Fraternity to be a sort of super-assassin, including being kicked, punched (similar to the comic example, but only until he finds a reason to why he's there), sliced open by various sharp objects, and smashed into a wall from the top of a moving train. Owie.
36 Chambers Of Shaolin has the protagonist subjected to such training alongside other trainees at the temple, including carrying heavy buckets of water with hands held straight to the side (with blades preventing trainees from lowering their arms) and having to ring a bell with a heavy, long-handled hammer. With one arm, as long as one's wrists can take it.
This describes poor Officer Jake Hoyt's Training Day to a t. Forced to smoke weed at gunpoint, beat up by two homeless guys, shot at by gang-bangers in Crenshaw.....
And it's all part of Harris' scheme to frame Hoyt for corruption so that Harris can steal the drug money he needs to pay off the Russian mob.
Jackie Chan's training scene in the Drunken Master films, where he has to do such things as sit-ups while hanging upside down to scoop up water in tiny teacups to fill a bucket at the top of his feet, and doing a 90-degree sitting stance for hours as punishment from his dad. He often tries to trick or cheat his way out of these, but is usually caught (filling the bucket from the well just graduates him to emptying it with the same motions as before, putting a bench behind his legs gets it kicked out from under him). Based on Jackie's real life training to be part of an acrobatic troupe.
Describes how Big Daddy trained Hit Girl (as in, his daughter) in Kick-Ass; in one scene she tests her bullet proof vest against live ammo.
The Bride from Kill Bill undergoes a hellish training regimen under the cruel master Pai Mei. Highlights of the training included carrying heavy buckets of water up and down the very long staircase to his temple, and learning to punch through blocks of wood with three-inch punches (which would help her escape her own casket years later).
Patches O'Houlihan in Dodgeball: A True Underdog Story trains the 'Average Joe's' dodgeball team by tossing wrenches at them, making them run through traffic, and even having a contraption which continuously shoots dodgeballs toward them at high speed.
Patches: If you can dodge traffic, you can dodge a ball!
Narrator: "A guy who came to Fight Club for the first time, his ass was a wad of cookie dough. After a few weeks, he was carved out of wood."
This prepares them quite nicely for "Project Mayhem". The induction for Project Mayhem is standing on the porch for three days while the leaders occasionally come out to insult you and tell you that don't make the grade and should leave.
Ninja Assassin contains quite some examples. Orphans, including the protagonist, are trained in martial arts and stealth skills and are brutally maimed, punished or killed for breaking the rules or failing. On one occasion, the protagonist has to walk on a wooden floor in front of his master without making any sound; when he does, his master beats the soles of his feet with a whip, so the protagonist has to do his training while bleeding from the wounds. On another occasion, his love interest refuses to cut a student whom she defeated in combat, and is subsequently scarred with a knife and locked in a wooden cage. However, the arguably most gruesome part of the training is when the protagonist is wounded in a sparring fight, and his master uses some kind of Dangerous Forbidden Technique on him, which leaves him screaming on the floor; the master then tells him that his next challenge is to survive for a night. Oh, and students that try to escape are captured and executed.
What separates this example from many others is the fact that, in the end, the master gets killed for being a twisted child-abusing son of a bitch, whereas, in many examples, the protagonist actually thanks the guy for beating him and turning him into an antisocial killing machine.
Apocalypse Now. Willard is shocked to read that Kurtz underwent US Airborne training at the age of 38. Willard went through the same training at 19 and it almost killed him.
Par for the course for the German team, and self-inflicted for the American team in Broken Lizard's Beerfest. How intense could it be? Among other things, they drink ram's piss.
Great Gam-Gam: If you can drink ram's piss... fuck you can drink anything!
In Batman Begins, Bruce Wayne is interned in a Bhutanese prison where he beats up the other prisoners, often by taking on large numbers simultaneously. This is after he's been travelling and learning several martial forms on his own for years, so he largely just sees these engagements as "practice." When Henri Ducard asks him to join the League ofShadows, his first task is finding a rare flower at the lower steps of their mountain fortress and carrying it to the top. Then he has to fight Ducard hand-to-hand, exhausted and barely able to stand. It only gets harder from there, but Ducard admits that it's more about mental training than physical.
Bloodsport — Dux suffers a few insane training moments including having his legs stretched out in the air while hanging on rope from the limbs.
G. I. Jane depicts the training regime of sailors who want to become part of a Navy SEAL-like unit. The movie goes so far as to show how one of them is tortured during SERE training by applying pressure on his broken leg as well as physically assaulting Jordan, busting up her lips, and threatening to rape her in front of her comrades.
Full Metal Jacket has such intense training, (coupled with hazing) that one recruit suffers a serious mental breakdown.It doesn't help that the drill sergeant was horribly abusive.
Naked Weapon has Madame M kidnap 40 teenage girls and force them to be trained by mercenaries on a remote island to be assassins. Any attempts to escape are punished by death. Six years later, several deadly tests imposed by M involve facing off against those same mercenaries in deadly combat, being forced to kill half their number, and the survivors being put in a cage with only one to come out alive. Not a very effective means of training assassins, but M ends up changing her mind and spares 3 of them. Oh, and during graduation, M has them drugged and brutally raped by the mercenaries to show the girls that their bodies are not their own and that they should have no qualms about using sex as a weapon.
In The Karate Kid, The Cobra Kai go through it to showcase their merciless attitude. Daniel undergoes Wax On, Wax Off training instead and winds up winning with it.
Although not as extreme as some examples, Eliza Doolittle goes through some pretty hellish training at the hands of Professor Higgins, being forced to recite her vowels for hours without food or rest. In addition, she is often on the receiving end of Higgins' rudeness.
Exaggerated in Edge of Tomorrow. Day after day, Rita gives Cage an unforgiving and literally murderous training routine, which typically ends with Cage killed either by the training robots or by Rita herself. But also justified, because she's exploiting his powers to give him months of training in a single day.
Jiro Dreams of Sushi: The training for Jiro's apprentices at his sushi restaurant. They start by squeezing the hot towels presented to the guests. The water is scalding and burns their handsóbut if the apprentice can't hand-squeeze the towels, he won't be able to hack the next ten years of training. Some just leave after the first day, the process is so daunting.
In Kingsman: The Secret Service, as stated by Merlin, the recruits are about to embark in the most dangerous job interview in the world, which includes tests such as surviving in a flooding room or making a HALO jump without a parachute. Averted as there's always a safety measure in place and even when the training seems to have claimed a life, it later turns out the recruit was an undercover agent.
