Oh my god that's just horrible
I'm in the middle of ground training my three year old gelding at the moment. Never, ever is he worked for more than half an hour and NEVER hard enough to make him sweat. He hasn't been worked with since he was a yearling and when I first got him I couldn't catch him, lead him, or even touch him. He would dance, spook, and bolt to avoid you.
Now with some patience and a little grass or grain I'm able to catch him without him spooking or throwing up his head like he used to. He will eat out of a bucket with me holding or standing next to it (absolutely refused to before). He eats out of my hand is now starting to approach me on his own.
He's ALMOST to the point were he will allow human approach and will stand to be rubbed and checked for ticks. He leads on a slack line now too :)
He stands tied, but doesn't bathe or pick up his feet...yet. We're working on being touched with strange things such as a lunge whip. He is VERY spooky about this still but always has plenty of room to 'escape' is needed and is frequently praised and calmed. I expect by the end of the week he'll be fine with having it rubbed all over.
I've done this without yelling, without hard punishment, without force. The worst 'punishment' he's ever received is not being able to eat grass for a moment or two. This was because he would constantly scoot when I went to brush him past the shoulder. He sure did stop that fast Don't hesitate to yield a whip and crack it. But think twice before you yield a whip and hit a horse, 'cause that horse might just hit you right on back.
