If you want to be RIPPED and don't mind blatant false advertising . . . you're gonna love this.
There's a product on sale right now on eBay for men: it's a silicone bodysuit that makes you look RIPPED. It goes over your torso and gives you jacked arms, pecs, and abs.
I think it would probably work best if you wear it under your shirt . . . as realistic as they try to make these things look, it'd be pretty clear they're fake from up close. But if you want to rock it shirtless, more power to you.
If you're interested, you can find them sellingon eBay for anywhere from $68 to $360.
