What Mark decries is extended periods of steady state cardio where you keep your heart rate above 85% of max. A slow jog for 45 minutes (assuming you're reasonably in shape) isn't chronic cardio. And Crossfit is anything but steady state. If anything, it's intervals, maybe some sprinting, etc.
That said, to answer your original question: Starting Strength. Work that for a few months until you have decent strength, then go from there.
