This video addresses the primary reason people struggle to build muscle, arguing that it's often not due to diet, sleep, or genetics, but rather insufficient muscle stimulation during training. The speaker contends that many individuals go through the motions without adequately challenging their muscles, resulting in a lack of growth.
The transcript doesn't explicitly state that increasing weight over reps is the only solution to the volume trap, but it strongly implies prioritizing quality over quantity. He suggests focusing on proper form, intensity (near failure), and mental engagement to maximize the effectiveness of each set, rather than simply increasing volume (sets and reps). The implication is that if you are properly stimulating your muscles with fewer, higher-quality sets, you may achieve better results than with numerous sets done with poor form and less intensity. Therefore, increasing weight, if done with proper form and intensity, would likely be more effective than simply increasing reps.
