I'm like you, grappler. I like to think I'm all the right things to be in tip top shape. I restrict my diet (we're talking about a lot of broccoli here); I train a lot of BJJ. And, yeah. I do plenty of kettlebell workouts and all that stuff too. But, when I see Steve Maxwell ... well, I just get sad, because he kicks so much ass and I realize I could be doing 100 times more.
It doesn't help that Steve is 60 years old and has been involved in BJJ for a couple decades now. That just makes me feel worse. His abs are make of steel and mine are made of something between Styrofoam and plastic (which, is not bad). I honestly don't know what a regular Janda sit-up is, nor do I really know much about my transversus abdominis muscle (except that it could be stronger and more six-packy). But, I know Steve is an excellent source of information and education for any athlete who's looking to improve his/her fitness. He's a true fitness guru (especially for combat athletes). Check it out.
