Seated Backbend (with towel)

Tandem Leaning: Tandem Stretching & Strengthening

Read the introduction.
Sit back to back with your tandem partner. You can sit in a wide leg pose or with your legs crossed.
Lift your arms above your head and grab an end of a towel with one hand and the other end with your other hand as they do the same.
Use your hands to lean into the towel as they do the same.
Use the towel to pull their arms toward your body while bending forward as they lean away from you.
Keep leaning away from them as they use the towel to pull your arms back and away from your body while bending forward.

Isometric	Your arms are isometrically contracting as you and your partner lean into the towel.
Concentric	Your arms are strengthening as you pull their arms down and toward your body.
Eccentric	Your arms are resistance stretching as they get pulled up and away from your body.
Reciprocal	The same holds true for your tandem partner.
