I'm not saying the study was flawed, cuz it might not have been, but...

The video did illustrate a possible reason for such a surprising result. The seated curl machine used in the video functioned completely differently from the laying machine. One used weight plates on a lever arm while the other used cables and pulleys.

Obviously this was the video illustrating the study and not actual footage from the study, so they might have made sure to control for this type of discrepancy, but you often have studies like this with surprising results that, if you look close enough, you'll find that they made a huge mistake.

Personally, I think if you have the option, Id suggest splitting your time between the two machines. They do have differences in their functionality like, one has your hips bent at 90° the other at 180°, the angle of gravity, etc. These differences, may or may not cause as drastic of a difference as the study suggests, but there will be a difference, if only in the small stabilizer muscles, and that matters. I personally advocate for using as many different types of training as is available. Free weights, functional trainers, flywheels, resistance bands, body weight, etc. Not necessarily in the same session or even the same "program". But maybe use 1 or 2 types for 6-8 weeks, then switch it up to different types.
