Areas trained: STOMACH, SIDES
With the KO8 fixed on the floor near your feet, lie on your back with the handles wrapped around your ankles. Bring your left knee up to your right elbow, lifting your shoulders and crunching your abs before rotating to the opposite side for the next rep.
‘The KO8 allows you to add resistance to regular moves like mountain climbers, sprints and squats, making them more challenging’
SAFETY TIP Keep your abs tense to protect your lower back
