Reading series
Three ways into the archive
If you prefer to read in sequence, the journal is organised into three running series. Each series is edited by one desk and reviewed by another.
Explainers
Short, structured pieces that define one idea at a time, such as aerobic threshold or training age. Suited to readers who want a clear starting point before moving to longer essays.

Reported pieces
Pieces built from visits, interviews and observation of ordinary training spaces. They place the research in the context of Indonesian schedules, climate and facilities.
Read the field notes
Evidence reviews
Summaries of what a group of studies suggests, with attention to participant age and to the limits of each design. Each review ends with open questions rather than conclusions.

Reading guide
How to get the most from an entry
Journal entries are written to be read slowly and revisited. A good habit is to read once for the argument, then return later with a notebook and mark the sentences that relate to your own routine. Questions that remain after a second reading often point to a conversation worth having with a coach or physician.
- Start with the summary box and the stated scope of the piece.
- Check the review date at the top of the page.
- Follow the linked glossary terms when a word is unfamiliar.
- Treat every example as an illustration, not as a template.
Information only. Journal entries explain general physiology and training concepts. They do not replace individual advice from a qualified health or exercise professional. See the disclaimer for details.
“Archives matter because training is slow. An essay from March can still help interpret a difficult week in October.”

Questions
About the journal
How often is new material published?
Roughly two entries a month. The pace is deliberately modest because each piece goes through a second-desk review described on the methodology page.
Are older entries updated?
Yes. Each entry is reviewed at least once a year, and the review date at the top of the page changes only when the content has actually been rechecked.
Can I propose a topic?
Yes. Send the question through the contact page. Topics are chosen on the basis of reader questions and available evidence, and not in exchange for payment.
