How to use it

Use

Stand upright, grasping the handles firmly for stability. Engage the abdominals and slowly raise the knees towards the chest, without jerking. Inhale as you return to the starting position and exhale as you contract your abdominals as you lift. For beginners, start with moderate knee lifts, then gradually increase the difficulty by adding more repetitions or lifting with straight legs.
