Chuck is an absolute animal. You can't stand anywhere near him without burning fat.
Chuck has been training my girlfriend for 2 years now, and the benefits are obvious. She is in much better shape than me, and she springs out of bed when it's time to go to the gym. Chuck is an awesome motivator and makes the gym fun (though he certainly won't go easy on you).
I've worked out alone my whole life, but have done a few sessions with him and still remember one tip he gave me last year to improve my dead-lift form. My feet were too wide apart for years, and when I changed my stance I was able to instantly add 20 pounds to the bar!
Chuck is a real inspiration. He practices what he preaches and his body is proof of the discipline he keeps in his daily routine.
