Here are some points I've accumulated to explain this.
"Trainees may choose to employee slight cheating techniques for the last repetition or two of a set. It has been suggested that very advanced trainees use cheating to increase training intensity, where as most other trainees use cheating as a means to decrease training intensity. Cheating should be considered an advanced training technique with inherent risks. Other safer and possibly more effective training techniques should be considered."
AND
"One way to cheat with your weight lifting is to do half reps. Some individuals find that this really kicks their training up a notch and helps them plough through a plateau when they experience one. What they will do is perform their usual set, using a full range of motion, then once fatigued, perform half reps (usually the second half of the concentric portion - so for example, the last half of a bicep curl.) This allows them to get a little extra muscle pump in there and push their body past the point of comfort.
While you likely won't see an incredibly amount of strength gains from your half reps strictly speaking, what it can help is to make your usual reps feel slightly easier so then, over time, you are able to bump the weight up there quicker, thus translating into faster gains.
So next time your results in the gym are stagnating slightly, consider cheating with your lifting. It isn't something you want to be doing every session, but it is a way to mix things up a little, add more interest to your workouts and get your body moving along the road to your goals once again."
AND
"This is a legitimate method used in weight lifting, say you are doing hack squat leg presses with heavy weight. You get 4-5 reps and realize that it is too heavy to do more, but if you cheat and stray from doing strict reps, you can use your hands to help you do 3, 4, or even 5 more reps.
In doing this, it helps to completely "shock" the muscle and you end up putting more stress on the muscle than if you have just stopped at 4 reps. The trick to this is not helping yourself out too much, just enough to finish the rep.
Also do this on your last set. Works great with bicep curls, everyone has probably cheated on accident in the beginning, but now you can explain how this is good. Use you're shoulders / back muscles to help curl the weight up.
Be creative and try it on other exercises. You will be surprised how this can take your training to the next level."
There is a lot of information about this; again only to be used by advanced lifters. And it is not saying to cheat all of the time just at some points. Good technique and form should never be sacrificed otherwise you get into bad habits but as a specific training method it can help.
