He touches on a couple of good points, like the differences between the belts, albeit a very brief overview. Then at the end he just barely gets into a common mistake I see of people who just walk around and do their entire workout with a belt just wrapped around their waist. I've researched it and follow the generally accepted principle that belts should mostly be used for near max lifts. And then they should be worn tight enough that when your done with the lift you have to take it off, or at least loosen it. If not, then you're not wearing it tight enough to really help you.
