Using Arm Slings
Arm slings are loops of leather or fabric which hang from the chinning bar (Fig. 7-a). They are an effective way to spare your the stress of hanging, but they must be used carefully because they can encourage your back to arch, increasing psoas involvement (Fig. 7-e). If you use arm slings, make a special effort to maintain an upward tilt of your pelvis to prevent your back from arching (Fig. 7-d).
To use, slide your arms through the loops to point just below your armpits (Fig. 7-b; you
may need to stand on a stool do this). The further in you can comfortably place the strap,
the less effort it will take to hold yourself in position.
We recommend wearing a sweatshirt to protect your skin from possible abrasion. Perform the exercise as detailed on the previous page
