tractor tires to flip. My personal record was 5x in a minute for the 300 lb ones, 12x a minute for the 200 lb ones..with acrylic nails bahaha. When we were done with the hour, we would lay on our mats in a pool of sweat, and it was like we were BATTLE BUDDIES. I would be in an amazing mood at work afterwards, the synapses from one thigh yelling across to the firing synapses of the other. I was the biggest person out there, but that made me proud. I even got to do push-ups with Marion Jones (Olympic runner) once! And yes, she was sadly the one embroiled in that doping scandal years ago....She is now a CG coach near me.
