To succeed in touching your toes, you must practice the Spine Stretch Forward while seated with legs extended, pulling the stomach in to actively round the back into a 'C' shape.

The exercise presented is the traditional 'Spine Stretch Forward' from the Pilates method, recognized for mobilizing the back and relaxing the posterior chain (expert opinion). Engaging the abdominals (pulling the stomach in) is an excellent technique to support the lower back and facilitate the rounding motion gently (expert opinion). However, using this 'C' curve to succeed in touching your toes is a double-edged sword. A randomized controlled trial (RCT) published in the *Journal of Back and Musculoskeletal Rehabilitation* shows that to increase flexibility in the backs of the legs in a targeted manner, it is more effective to stabilize the pelvis and initiate movement from the hips. Indeed, actively rounding the back shifts a large portion of the tension from the legs to the spine, which can create uncomfortable tension in individuals who are very stiff (expert opinion). This exercise remains an excellent general mobility routine for posture, but proves less targeted for specifically releasing the back of the thighs.

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.
