Apparently Arnold Schwarzenegger's son Chris lost a lot of weight and then promptly put it all back on. I think that's what they're talking about, the source material from this place isn't always entirely clear. And I didn't know that Arnold Schwarzenegger had a son named Chris. Maybe they don't talk about him much if you know what I mean. Just look at him of course you know what I mean.
The bigger story here is how he's driving and doing things all by himself! They didn't say where he was going but I'd guess to his job as a bag boy in the grocery store or maybe the guy that collects the carts since he looks pretty strong. Keep going Chris! You're doing such a good job!
