The short box series on reformer can be used as essential level preps or full-blown intermediate exercises. Feet pulling the foot strap taut as you utilize the strength of your core to articulate your spine. The movement of your arms create longer levers which increases the difficulty of this exercise. The arm movement and spinal twist are assisted by engaged obliques.
Below are three exercises for the short box followed by a full video:
Round Back for Short Box:
Start sitting up straight, feet pulling strap taut, neutral spine, palms on top of one another in your lap. Inhale to prepare, exhale to tuck your pelvis and roll onto your back pockets.
Inhale to lift your arms over head, maintaining that round thoracic spine.
Turn abs on even more, pulling belly toward spine, and roll over your thighs – maintaining that c-curve of your spine.
Exhale to stack back up to a neutral spine from tail to head.
Straight Back for Short Box:
Begin by sitting upright on your box with a neutral spine, feet pulling strap taut. With bar overhead, pull on opposite ends of the bar to engage your arms.
