Bodybuilding broke into the mainstream during the sportโ€™s so-called โ€œGolden Eraโ€โ€”a time when icons like Frank Zane, Lee Haney, and Arnold Schwarzenegger competed on the Olympia stage with aesthetically minded physiques that put a premium on size, symmetry, and a certain grace and fluidity. That was all well and good for the โ€˜60s, โ€˜70s, and โ€˜80s, but the 90โ€™s belonged to the mass monsters.

This was a time when all athletesโ€”ranging from professional wrestlers to baseball playersโ€”began to grow to Olympia proportions. So it only made sense for the bodybuilders themselves to getโ€”wellโ€”even bigger than that. Broader shoulders, barrel chests, pants-splitting quads, and scales tipping well over 270-300 (sometimes even more!) pounds became a necessity for anyone with dreams of a Sandow.

Thus began the era of the โ€œMass Monstersโ€, and while thereโ€™s no clear starting point to the trend, you can begin with the rise of Dorian Yates, whose hulking frame led to an Olympia dynasty in the early โ€™90s, coming right after that of Lee Haney, one of the most aesthetic of all the classic โ€œGolden Ageโ€ competitors. It was a changing of the guard for the entire world of bodybuilding, where pleasing aesthetics gave way to jaw-dropping sizeโ€”and if you wanted to win, you needed plenty of mass to go around.

While the art of bodybuilding is always at the forefront of the sport, thereโ€™s nothing wrong with gazing in awe at some of the freakish physiques that came from the mass monsters eraโ€”an era that still influences bodybuilders and bodybuilding stages today.
