I’ve built successful programs both ways. Here’s what most of this debate gets wrong—and how to know which one you should be using. By Jim Stoppani, Ph.D. Over the years, I’ve designed a number of popular muscle-building programs using both full-body training and body-part splits. I’ve also had plenty of debates about which approach works better. On one end is the traditional bro split—the Monday-chest-and-triceps, Tuesday-back-and-biceps template that’s been a bodybuilding staple for decades.

You’ve heard there’s a limit and the rest gets wasted. A 2023 study went looking for that ceiling—and couldn’t find it! By Jim Stoppani, Ph.D. You’re at dinner and there’s a second chicken breast sitting on the platter. You want it.

If you’ve spent any time around longevity, recovery, or performance-focused wellness, you’ve probably heard of NAD+. It’s often discussed as though it were a secret ingredient for more energy, better aging, or improved performance. But what is NAD+ actually doing inside your body?

Walk into almost any supplement store and you'll find hundreds of products promising more muscle, better recovery, sharper cognition, deeper sleep, or a longer life. It’s important to remember, however, that more supplements don't necessarily mean better results. The truth is, for someone who cares about both physique and longevity, the ideal supplement strategy is surprisingly boring. Start with the fundamentals. Then add supplements with a reasonable evidence base and a clear purpose.

When people talk about fitness, they often separate metabolism, hormones, body composition, and performance into completely different categories. Your metabolism is discussed in one conversation then hormones are discussed in another, followed by body composition getting its own conversation.
