Seated Backbend

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 link hands with them (similar to picture one only with both hands on bottom or top).
Use your arms to lean away from them as they lean away from you.
Pull their arms toward your body while bending forward as they lean away from you.
Keep leaning away from them as they pull your arms back and away from your body while bending forward.

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