Some lifters tell you it's alright to cheat. Arnold Schwarzenegger himself said it was an acceptable method of promoting muscle growth. During his bodybuilding days, Schwarzenegger popularized "cheat curl" – a technique that sacrifices form for sheer volume of work.
Cheat Retries May Be Effective – But for today's training of Men's Health Fitness Director Ebenezer Samuel, C.S.C.S., we will ignore Arnold's methods. A strict shape is the rule of the day, so you can really isolate the tips of your biceps for a pump-by-the-books pump.
"We focus on the upper half of the bicep curl movement with this curl and do it in a way that will not cheat you," says Samuel.
