Over 40

“Give it 48 hours.” It’s the most repeated number in strength training — repeated in gyms, on forums, in programmes, and by coaches who mean well. Heavy lifting “fries your CNS,” and the CNS apparently needs two days to reboot. The advice lands on the right answer through the wrong mechanism. Which matters, because if you recover on a timeline you can actually measure, you recover differently. This post is the third in a short series on central fatigue. The primer on what CNS fatigue is and how HRV catches it gives you the framework. The myth put on trial handles whether heavy lifting “fries” anything at all. This one answers the question both of those raise but don’t settle: how long does it actually take to recover, hour by hour? ...

A study published in August 2026 put creatine in front of a question the supplement industry has never been able to answer honestly: does it do anything for a person who is not training at all? The short answer is yes, a little, and the size of the “little” is the entire story. Adults aged 45 to 65 who took 10 grams of creatine monohydrate daily for twelve weeks gained roughly 2.4 pounds of lean tissue without following any exercise programme. They also got stronger on leg press and bench press. That was against placebo, so it is not a “they felt better” result. ...

If you lift weights and you snowboard, you already know the pattern. You train for months, you book the trip, you show up — and then you stand in a rental shop being handed a board because it’s “about your height.” Nobody asked what the board’s camber profile was. Nobody asked about waist width. And you ride away on something that either fights you for six days or, occasionally, feels inexplicably good — and you never find out why. ...

Type “does heavy lifting fry your CNS?” into Google and you’ll get a wall of confident answers. Yes, obviously — that’s why you need 48 hours between heavy sessions. Your central nervous system is a battery, and every hard set drains it. It’s one of the most repeated claims in the gym. It is also, as a mechanistic claim, substantially wrong — and the way it’s wrong matters, because it leads men over 40 to train around a threat that isn’t the real one. ...

If you wear a watch or a band, you know the picture: it’s eleven at night, you’re two thousand steps short, so you walk laps around your building. The watch sets off fireworks and you feel like you’ve done your duty for the day. That number — 10,000 — you’ve assumed is a scientific standard. It isn’t. It was a slogan invented in 1965 by a Japanese clock company to sell pedometers, and at the time there was no research behind it at all. The science only got bolted on decades later. ...

Search “which protein powder is best” and you’ll get a different answer from every page. Whey is the king. No, casein for the overnight window. No, soy is just as good and cheaper. No, pea, because dairy wrecks your gut. Here’s why the arguments never resolve: they’re ranking proteins on a measurement that changes depending on how long you watch. Run a muscle-protein-synthesis test for three hours after a scoop and whey wins. Run the same test for six hours and casein catches up. Measure what actually leaves your gut and gets retained, and pea ties milk protein outright. Every one of those studies is real, well-conducted, and correct. They just answer different questions. ...

Walk down any supplement aisle and collagen has taken over half the shelf. The pitch is always the same: your collagen declines after 40, so take this and get it back. Skin, hair, nails, joints, “glow” — one powder promising everything. Here’s what that pitch quietly leaves out. Collagen is not one thing with one effect. The strongest evidence for it is narrow, specific, and comes with conditions attached. The evidence for the thing people actually buy it for — bigger muscles — is not just weak, it’s negative. ...

Here’s a quiet confession most lifters over 40 would never say out loud: they’ve spent thousands of hours making their body do things, and almost no hours learning to feel what it’s telling them. Strength is output. You know output — sets, reps, load, progressive overload. But there’s a second signal you’ve been ignoring, and it’s the one your body uses to keep you out of pain, to tell you when to push and when to back off, to keep one bad rep from becoming a six-month injury. ...

Here’s a feeling every lifter over 40 knows, even if they’ve never named it. You show up. Your muscles don’t even hurt. Your warm-up feels fine. Then you get under a bar that you moved easily last week — and it feels like it’s bolted to the floor. Your coordination is slightly off. Your drive is gone. You grind through it anyway, because that’s what men do, and the number still won’t budge. ...

Sometime around forty, men start describing their own bodies the way they’d describe the rain — “I’m just stiff now.” It’s said with the resignation of a weather report, as if stiffness were a thing that happened to them rather than a thing they stopped doing. That one sentence contains an entire theory of aging, and it’s wrong. Stiffness is not a property of getting older. It’s the consequence of a skill — moving through a full range of motion — that quietly got dropped from the training menu the moment the schedule got busy. ...
