Training, recovery and performance
Put your resting calorie number in context
Separate resting energy use from total daily needs, understand test preparation and bring better questions to your results discussion.
Read DiagnosticsUnderstand your aerobic fitness test
Know what the oxygen-use number means, what a graded test involves and how to prepare without guessing.
Read LongevityNAD+: what the evidence actually shows
NAD+ precursors reliably raise a blood marker. Whether that changes anything you would feel is a different question, and the human trials answer it far less kindly than the marketing does.
Read TrainingMake a shorter session count
Judge a short session by its purpose, progression and place in your week, not by the clock alone.
Read TrainingChoose the setting that fits your training
Separate the room from the coaching. Compare reserved equipment, shared space and the questions that help you choose a training setting.
Read TrainingFind a coaching rhythm you can keep
A practical framework for deciding how much coaching you need, what to do between appointments and when to reassess your training schedule.
Read ClubYour first visit, without the guesswork
A practical guide to the conversation, studio tour and separately scheduled next steps, with questions to help you decide whether Aeon fits your week.
Read PositioningWhat a luxury gym should actually mean
The word luxury has been used to sell finishes. It should describe coaching depth, supervision ratio, diagnostics and clinical continuity — the variables that actually change what happens to your body.
Read TestingBody composition scans: reading your results
None of these methods measures body fat directly. Here is what each one estimates, how wide its error bars are in published validation studies, and which numbers on your report are worth acting on.
Read TrainingSemi-private training: what you actually get
Supervision ratio changes how hard people train and how much they gain. Here is the evidence behind semi-private coaching, and where it genuinely falls short of one-on-one.
Read PerformanceSport-specific training: who actually needs it
Plenty of athletes are limited by general strength and power rather than by a missing sport-specific drill. Here is how specificity actually works, and what changes for junior athletes.
Read RecoverySports massage vs deep tissue massage
The two names describe intent and timing more than they describe distinct techniques. Here is what the research supports, and which popular explanations it does not.
Read TrainingIs personal training worth it?
Supervision changes how people train, not just what program they follow. Here is what the studies show, and who genuinely does fine without a coach.
Read PerformancePickleball injuries and what to train
Reported pickleball injuries cluster by age and body region, but the headline numbers count hospital visits rather than risk per game. Here is the careful reading.
Read PerformanceStrength training for golfers
Resistance training is associated with meaningful gains in clubhead speed and distance across the literature. The size of the effect, and what it does to your score, is where honesty is required.
Read ClubHow to choose a trainer in North Atlanta
What to look for, what to ask, and which credentials mean what. These are editorial criteria rather than research-backed guarantees, and they are the ones we would use ourselves.
Read TrainingStrength training over 40
Turning 40 does not trigger a decline. The published changes in muscle mass and strength between 30 and 50 are small, and disuse explains more than age does.
ReadMost fitness writing is either a sales page in disguise or a summary of a study nobody read. We are trying to do something narrower and more useful: answer the questions members actually ask us on the floor, in the same words we would use in person, with the sources attached.
A few ground rules we hold ourselves to.
We name the limits of the evidence. When the research is mixed, we say it is mixed. Our sports massage page is a good example — the honest answer is that it does not reliably improve strength, sprint or fatigue outcomes, so we do not sell it as though it does.
We do not give medical advice. Anything touching medication, hormones, peptides, labs or an active injury belongs in a room with a licensed provider who has your history in front of them. Articles in this library point you toward that conversation rather than replacing it.

Bring it to a consultation. Thirty minutes with a coach or clinician answers more than an hour of reading.
