Speediance Gym Monster 2S

Primary upstairs machine with massive real-world usage.

Speediance Gym Monster 2S

It is significantly quieter than my original unit and office-friendly. I have logged 1,296,447 lbs of total volume across both Speediance machines with a best single session of 35,305 lbs in 50 minutes.

Post-V3.1 firmware changes made cable behavior worse for my training style. I have publicly criticized the retraction behavior and app responsiveness issues.

Even with software frustrations, the physical utility for daily heavy cable work is high enough that it remains a core part of my training.
