This exercises is designed to be performed with resistance tubes or bands. Resistance Tube exercises offer a portable solution for full body conditioning and full range-of-motion training.
Sit down on the ground with legs extended in front of the body and the resistance tube around the soles of the feet. Arms should be extended, gripping the handles with palms facing each other.
Sitting up tall, pull the resistance tube towards the core, bending at the elbows and squeezing shoulder blades together.
Pause, and then slowly return the tube to the starting position.
