How to: Single-Arm & Leg Jackknife

Primary Muscles Used:Abs, Rectus Abdominis

Exercise Families:Trunk Flexion

Trainer:Kelsey Wells

  1. Start by lying on your back on a yoga mat with your left arm extended above your head and your right arm out to the side so that it creates a 90-degree angle with your torso. This is your starting position.
  2. Inhale. Exhale. Raise your right leg off the mat to create a 90-degree angle at your hips. At the same time, bring your left hand towards your right foot – slowly lifting your head, shoulder blades and torso off the floor, ensuring that your right shoulder remains pressed into the mat.
  3. Inhale. Slowly lower your leg and arm to return to the starting position, but without resting them on the mat. Complete half of the specified amount of repetitions on the same side before completing the remaining repetitions on the other side.
