It is with deepest regret to inform you all that Lynn McCrossin, known as the Pec Panther and the founder of female pec bouncing, lost her battle to cancer on June 18, 2015, just a few days after her birthday. Without her talent, we might have never known what muscle control was. This site would definitely not be here if it wasn't for her. Words can't describe how sad we truly are to lose the Queen of Pec Bouncing. There will never be another Pec Panther. May she Rest in Peace.
This is a place for fans and performers of female muscle control. Discuss, view, and post your favorite clips of females performing the ultimate in flexing (bicep bounce, pec/chest bouncing, quad shaking/bouncing, glute bouncing, ab rolls, etc.)Think of it as a Youtube/Facebook for muscle control performers and their fans.
