Tren Nation - How an obscure bovine steroid became gym Gen Z's favorite social-media muscle flex.

Not anabolic steroids. Not testosterone. Not creatine or multivitamins or a high-protein diet. No, Frank and Jesse (who both spoke on condition of anonymity because trenbolone is deemed illegal) immediately jump to trenbolone, which has quickly developed a rep for increasing muscularity and decreasing body fat all at once. Among bodybuilders it's known as the god of all steroids for its potency. To teens and young men, it's simply tren, a ticket to the prototypical social-media-friendly physique. Why? Frank, who's now 18, explains tren's growing popularity with all the confidence and expertise of someone who Googled tren once (mostly to see how jacked it made cows), watched hundreds of hours of tren content on Tik Tok, and made a ton of tren jokes. If the only thing you care about is putting on muscle, he says, it really does seem like tren is the thing to take.

Luckily, new tech can help. Listen up. An estimated 15 percent of American adults-that's about 38 million peoplehave some level of hearing loss, according to the CDC. Research increasingly suggests that untreated hearing loss can lead to other significant health issues, including depression and Alzheimer's disease.

Back-Round Check! - Tap into next-level total-body strength and supercharge muscle gains by learning when and how) to round your back in the gym.

Lift with your legs, not with your back. It's a cue many trainers use anytime you bend down to lift something heavy. It makes sense, too, since conventional wisdom holds that rounding your back with heavy weight leads to injury. But if you look closely at a strongman like Tom Stoltman hoisting a 300-kilogram (661-pound) Atlas stone, you'll notice that his spine isn't ramrod straight at all. Instead, he's almost hunching forward, curling his entire spine around the stone. And if you scroll fitness social media long enough, you may come across an exercise called the Jefferson curl, which asks you to stand holding a light barbell, then lower the barbell while simultaneously rounding your back as much as possible.

Christian Mccaffrey is Him - He's entering his eighth season in the NFL, but the league's most electric running back is not slowing down.

Every off-season for the past seven years, Christian McCaffrey, the San Francisco 49ers' All-Pro running back, has met up with Brian Kula, C.S.C.S., a trainer he's worked with since eighth grade. They talk about any injuries and any niggling pain from the previous season, do a battery of strength and movement tests, and then create a program "to turn CMC back on."
