Evidence instead of gut feeling.
Training after 40 is not “the old training, just slower”. It follows different rules – and they can be backed up.
Three things every guidebook delivers.
Built for 40+
We don’t just change numbers, we change the system: intensity, weekly split, warm-up, rest, nutrition and sleep follow what changes after 40.
With sources
Every key claim has a traceable study behind it in the source list. Where research is thin – for example on women – we say so openly.
Actionable
A fixed weekly plan, warm-ups to follow and tips to check off. Not knowledge gathering dust on a shelf, but a system for everyday life.
Four assumptions that hold you back.
Your metabolism slows down at 40.
Total energy expenditure stays remarkably stable between 20 and 60. What changes: muscle mass and everyday movement.
Heavy training is bad for bones and joints after 40.
High-load training measurably increases bone mineral density. Your skeleton needs the load, not protection from it.
After 40 you need forever to recover.
A meta-analysis of 36 studies found no age-related difference in strength loss after hard training. What takes longer: tendons and joints – they need a more controlled increase in load.
Testosterone boosters solve the problem.
Levels decline by roughly 1–2 % per year after 40. According to the guidebook, strength training, sleep, less body fat and less alcohol work better than any supplement on the shelf.
Statements from Guidebook No. 3 (men); the related studies are listed in the book’s source list.
At 20 vs. past 40: an excerpt.
| Topic | At 20 | Past 40 |
|---|---|---|
| Weekly split | Push-pull-legs, 1×/week | Upper/lower split, 2×/week |
| Exercise choice when unsure | Free weights forgave mistakes | Prefer machines – they guide the movement |
| Mobility | Barely any dedicated mobility work | 15–20 min of mobility on rest days |
| Testosterone | At its natural peak | Declines gradually, ~1–2 % per year |
| And 7 more differences – in the guidebook | ||
