Krizo, Andrew Jacked, and Mike Sommerfeld teamed up for an intense arm session as the New York Pro approaches
As the 2026 New York Pro gets closer, some of bodybuilding’s biggest names are ramping up the intensity in the gym, and a recent training session featuring Michal Krizo, Andrew Jacked, and Mike Sommerfeld has fans talking.
The trio linked up for a massive arm workout posted on YouTube, giving fans a closer look at the kind of training fueling their preparations ahead of one of the biggest shows of the season.
Krizo, who continues to build momentum as one of the most dangerous mass monsters in Men’s Open, looked locked in throughout the session. Andrew Jacked brought his trademark combination of size and aesthetics, while Classic Physique standout Mike Sommerfeld held his own despite competing in a completely different division.

Throughout the session, the chemistry between the three bodybuilders stood out almost as much as the training itself.

Krizo has continued to refine his conditioning while maintaining overwhelming size, something many fans believe could make him a legitimate title threat this season. Andrew Jacked remains one of the most naturally aesthetic mass monsters in bodybuilding, combining towering structure with flowing lines and improved density.
Meanwhile, Sommerfeld continues to establish himself as one of the elite names in Classic Physique, known for his polished conditioning and detail.
