Training in a group stimulates greater endorphin production, increases tolerance to physical exertion, and reinforces the motivation to push one's limits.

Research broadly supports the idea that shared exercise offers significant psychological and physical benefits. An experimental study from the University of Oxford, led by Emma Cohen and published in Biology Letters, shows that athletes training in a synchronized manner double their pain tolerance, a key indirect indicator of endorphin secretion. This effect appears to be closely linked to the coordination of group movements, which naturally fosters cohesion and well-being. Furthermore, a meta-analysis on the Köhler motivational effect shows that exercising with partners encourages more intense and persistent effort. However, it should be noted: this peak in endorphins is primarily documented during collective activities that are coordinated and rhythmic (such as team rowing sessions or group fitness classes), rather than for purely individual exercises performed simply side-by-side in a gym.
