Got a tight back? Here's a fun way to open your spine and stretch your hamstrings too. I call this Backpack.

• Stand back to back with your partner. Lock elbows and Partner #1 bends her knees and places her bum under Partner #2's bum.
• Then Partner #1 slowly folds forward, lifting Partner #2 off the ground and onto her back. Stay like this until either partner is ready to come down. To release, Partner #1 slowly stands back up and then you can switch roles.
• After you both have a turn, take a step apart and fold forward. Reach for each other's hands or legs and hang here for a few deep breaths, releasing your lower back and stretching through the backs of the legs. Stand up when you're ready.
