Neck Glide
Practise sliding the head gently backward without turning the movement into a nod or shifting the torso.

Posture Zebra uses exercise-specific camera views and visible movement cues. The goal is not a “perfect” posture—it is more control, comfortable range, balance, and consistency.
Practise sliding the head gently backward without turning the movement into a nod or shifting the torso.
Move both arms through a comfortable overhead range while keeping the visible trunk steady and the sides moving together.
Rotate the shoulder line over a quiet seated base, alternating directions without rushing through the centre.
Glide the pelvis forward gently from a half-kneeling base while the visible torso remains comfortably tall.
Reach opposite arm and leg from all fours, then return to a stable base before changing sides.
Build a steady forearm support line while keeping the required shoulder, hip, knee, and ankle landmarks visible.
Practise a supported side line using the clearly visible side rather than asking the camera to infer hidden joints.
Raise and lower the hips with a visible top position and a deliberate return instead of chasing maximum height.
Practise a comfortable squat while watching broad knee-to-foot paths, left-right timing, and visible trunk symmetry.
Build a centred single-leg hold with a soft stance knee and visible shoulders and hips.
An iPhone camera estimates visible body landmarks. It cannot see pain, muscle activity, spinal segments, joint loading, or the reason a movement feels difficult. Stay within a comfortable range and stop if you feel pain, dizziness, numbness, or unusual shortness of breath.
