B12 absorption drops after 50 — deficiency runs 20–40% in older adults
The daily requirement is 2.4 micrograms, the smallest of any vitamin. The problem is not how much you eat; it is that ageing stomachs stop prising B12 off the protein it arrives attached to.
Creatine comes down to 5g of monohydrate — and skipping the loading phase
The labels carry a lot of adjectives, but only three things are worth comparing: the form, the serving size, and third-party testing. The rest just moves the price.
Salmonella in greens powder again — dried does not mean sterile
The assumption that drying kills bacteria is wrong. Without a validated kill step, dehydration does not eliminate salmonella, and it persists in dry powder for long stretches.
Start with the barbell once dumbbells feel easy for 5–10 reps
What keeps people in the machine section is usually not strength — it is not knowing what to do over there. Climb a dumbbell ladder first and the day you pick up the bar becomes a formality.
You do not have to enjoy exercise — treat it like brushing your teeth
What someone who hates exercise needs is not a better programme but a different category. Move it out of hobbies and into hygiene.
If you already know what to do and still are not doing it, information is not the problem
Some problems do not dissolve when you watch another video or buy another programme. Not because the material is missing, but because direction and support are.
What the Big 3 miss: power, rotation, and awkward objects — and where they go
Squat, bench and deadlift build maximal strength. Moving fast, rotating under load, and handling something that is not balanced have to come from somewhere else.
Resistance training after oral cancer treatment increased lean mass and strength
That comes from a systematic review of 24 studies across nine databases. Supervised, individualised programmes produced higher adherence and better functional outcomes.
Keeping mTORC1 switched on does not grow muscle evenly — fibre types diverged
In a mouse model with the growth signal permanently on, type I and IIa fibres were largely untouched while type IIx fibres either swelled abnormally or went somewhere else entirely. The pathway is not a volume knob.
Volume beats intensity for hypertrophy — up to about 30–40 sets a week
Meta-analyses consistently find more weekly sets per muscle means more growth, but returns diminish past roughly 30–40. Low-volume training taken to failure still works when time is short.
Four hours of sleep costs you about 2–3% of your strength
A meta-analysis of 69 studies found performance drops roughly 0.4% for every hour awake before training. Strength suffers less than skill, but enough to ruin a one-rep max attempt.
Muscle growth correlated with strength at r=0.92 — the number is inflated
A 15-week study of 39 untrained men reported a 0.92 correlation between hypertrophy and strength gains. It came from a statistical method that returns 0.83 on data with no relationship at all.
Digestive enzyme supplements do not help you absorb more protein
Bloating after a high-protein meal is usually about portion size, eating speed or lactose — not an enzyme shortage. Gastroenterologists put those first, and the supplement nowhere.
