Allow me to quote:
"I have a perfect Robert Lemm treadmill, excellent. I haven't used it in 10 years. Nothing beats the jenny for conditioning. I used to do flirtpole and springpole work, but not so much anymore. I believe in strength-conditioning too. I'll hook a chain to a dog's harness on certain days when they're running the jenny so they can get some weight resistance training. Anyone who doesn't believe in strength training isn't winning consistently in top competition today."
