Fitness-mad mum's tendon 'snaps like a gunshot' during home exercise workout

A fitness-mad mum found her Achilles heel - after trialling a new workout caused her tendon to snap like a gunshot. Tiffany Van Dyke, 41, was recording a preview for a new work out when her achilles tendon ruptured loudly. Immediately after the audible crack the high school science teacher and online health coach knew something was wrong. She hobbled to an armchair and attempted to sit down as the excruciating pain set in and she could feel the tendon rolling up her leg.
