Testing chest activation at different angles from @jeffnippard
The creator conducts a personal experiment to test upper chest muscle activation across various bench press incline angles. He uses an EMG sensor to measure activation from 0 to 90 degrees, displaying the percentage data for each specific angle on screen. He concludes by analyzing the results, debunking the strict necessity of the 45-degree 'golden angle', and advising viewers to choose the incline that feels best for their individual biomechanics.

Transcript excerpt
People think a 45 degree incline is the best angle for the upper chest, but I wanted to test this out for myself, so I measured my upper pec activation at every incline from flat to vertical. At zero degrees, I expected a fairly low reading, but I actually got 59% upper chest activation. Next was 15 degrees, which I expected to be higher, and, yeah, 64%. At 25 degrees, I good, ready for this, 66%. So activation is going up as the incline goes up, but not by much. Now let's test the golden angle, 45 degrees. That incline gave me a reading of 67%. Let's see if it keeps going up at 65 degrees. No. Back down to 60%, and then 90 degrees dropped way back to 35%. So 45 degrees one, but it was basically the same from 15 to tier, and if you have less arch than me, a slightly lower incline might actually work better on just one subject, and activation may not predict growth. The real takeaway, pick an angle that you feel working and get strong at it.
