To improve overhead arm mobility, one should test thoracic spine rotation on each side. If one side is restricted, a kneeling rotational stretching exercise combined with deep breathing at the end range (3 cycles) can immediately unlock shoulder range of motion.

The link between thoracic spine mobility and shoulder movement is well-documented in biomechanical research. An observational study by Kebaetse et al. (1999) shows that restriction in the thoracic region directly limits arm elevation. Furthermore, a randomized controlled trial (2020) confirmed that working on the mobility of this region significantly improves shoulder movement. Regarding the rapid release effect presented by the creator, a crossover trial (2026) highlighted that a single mobility exercise session does indeed increase rotation range of motion in the short term. However, a systematic literature review (2016) notes that these instantaneous gains are primarily neurological in origin (a temporary increase in stretch tolerance) and that maintaining them long-term requires regular practice. Finally, deep breathing at the end range is a validated kinesiology technique for modulating nervous system activity and promoting muscle relaxation.

What the graded evidence says

Evidence: B

Effect: mechanism of range-of-motion gains; acute effects of stretching on performance — increased ROM largely attributable to greater stretch tolerance (sensory) in the short-to-medium term; prolonged static stretching immediately before activity can transiently reduce strength/power
Measured on: healthy active individuals

Whether long-term stretching also changes muscle structure is debated; short-to-medium-term gains are mostly explained by increased stretch tolerance. Effects on injury prevention are modest and separate from flexibility gains.
