Timestamp Quote (auto-caption; lightly cleaned for readability)
1:01:13–1:01:15 “Um obviously, walking is important, but it’s not uh [a separate section].”
1:01:21–1:01:24 “So, I’ll aim to walk 10 to 12 K steps every day.”
1:01:24–1:01:26 “I’ve incorporated weighted vest walking as well already in 2025.”
1:01:36–1:01:39 “And if you just wear even a small weighted vest like 5, 10 kilos in your everyday activities…”
1:01:52–1:02:00 “So, I’m actually a huge fan of weighted vests now. And I’m going to get like a very light vest, 5, 10 kilos, and I’m going to get a super heavy vest, 30 to 40 kilos, for doing weighted calisthenics…”
1:02:05–1:02:08 “So, it’s also kind of low zone one, zone two cardio if you have a heavy vest and you’re walking.”

Note: OPTIMALS.md also cites ~1:01:10–1:01:25 for the combined walking/steps line — matches this pass.

Walking is incidental (warm-up: “easy jog or brisk walk”); primary topic is sprinting — see intervals.

siimland.co — exact quotes

Page: My Longevity Routine (checked 2026-09-18)

“A higher daily step count is linearly associated with lower all-cause mortality and cardiovascular disease (R; R). A 2020 JAMA study showed that walking 12,000 steps per day was associated with a 65% lower risk of mortality compared to taking 4000 steps per day (R). There were no significant observed benefits beyond 12,000 steps.”

“Overall, it’s recommended to get at least 8-10,000 steps a day. I personally try to aim for at least 10-12,000 steps a day.”
