The Arm Day Mistake 90% Of Guys Make

Huge pump on arm day, zero growth a month later? You're probably making the same mistake almost every guy in the gym makes, and it's not a bad exercise or bad form. In this video, you'll learn why chasing the pump doesn't build bigger arms, why most curl variations train the same weak position, why so many of your sets don't actually count, and the one mistake in how arm day is built that ties it all together. Then you'll get a simple weekly arm setup that makes almost every set count. Everything here is based on research, including a review of 25 studies on training frequency and a study where overhead triceps extensions built about 1.4 times more muscle than pushdowns. Measure your arms cold in the morning today, follow the setup, and check again in four weeks. Subscribe for the full series on building a bigger, wider upper body the smart way.
