The physiques of early 20th-century bodybuilders look noticeably different from the later chiselled, V-tapered standard. Compare bronze-era pioneer Eugen Sandow to silver-era icon Steve Reeves and the contrast is clear.
Where modern physiques prioritise a narrow waist and wider lats, early lifters often carried thicker, more blocky cores – closer to what you might see in today’s CrossFit athletes. The idea has gained traction online, including in a recent YouTube video by creator NattyLife. Here’s how differences in training styles and equipment helped shape those physiques.
Heavy, Unconventional Lifting
Bronze-era training was simple by today’s standards. With little more than barbells, dumbbells and kettlebells, lifters relied on heavy, often unconventional movements to build strength – think single-arm deadlifts, bent presses and other awkward lifts.
These placed a significant demand on the trunk, working the core through flexion, anti-flexion, extension, anti-extension, rotation, anti-rotation and lateral flexion. The result was a midsection constantly forced to stabilise under load from multiple angles. Over time, this can contribute to a thicker, stronger, more robust core.
No Machines, More Full-Body Demand
Machines make it easier to isolate specific muscles while limiting involvement elsewhere – but early lifters didn’t have that option.
Without access to machines, racks or even basic benches, most exercises required full-body coordination. Training the back, for example, meant supporting and moving weight through the entire body, increasing the demand on the core.

The Shift in Bodybuilding Aesthetics
As bodybuilding evolved, so did its aesthetic ideals. A wider upper body and narrower waist became the gold standard, reinforced by posing trends, judging criteria and advances in gym equipment.
Movements like pull-ups and lat pulldowns allowed lifters to build upper-body width without the same level of core loading. At the same time, training strategies began to favour minimising waist growth through more targeted exercise selection.
Different Training, Different Physique
The thicker midsections seen in bronze-era physiques weren’t necessarily the result of superior development, but different training demands.
Where modern programmes often isolate muscle groups, early lifting required the body to work as a unit. The result is a simple reminder: physique often reflects function. Change how you train, and your body will adapt accordingly.
