Unapologetically Amanda Koh on Instagram: "This is a very different modality of movement from what @justine.teng is conditioned to do. Many people are surprised to realise that spine corrector exercises when done with precision, only LOOK easy! I often do 5-8 reps of most exercises with my clients and they feel the effects for the next couple of days. With Justine we are aiming for 3-5 reps of most exercises, done with frequency."
