Yesterday was the anniversary of Susan's Thunderbolt membership. You’ve likely heard the legend (and it's entirely true): Susan's first workout at Thunderbolt was Murph πŸƒβ€β™€οΈπŸ₯³ and she kept coming back!

So this means Susan has been a member for 11 years πŸŽ‰

She's done Murph 15+ times πŸŽ‰

As of today, she's attended 2,663 classes πŸŽ‰

If you ask us, her secret to success is consistency. Through the highs and lows, through different seasons of life, through times of PRs and pushing it, through times of injuries and status quo, Susan keeps showing up.

Cheers to 11 years, Susan πŸ’ͺ🏽 Thanks for being such an important part of the Thunderbolt family.
