Even if your middle-aged friends, family members and coworkers can't quite make the stretch to even do yoga anymore, they'll still get a good, tummy-flexing laugh upon receiving one of the hysterical mat-based missives. And just maybe they'll be motivated to use the garrulous greeting cards as a guide to a whole new workout program, one befitting their mature years.
