Repeat after me : "intensity is not substitute for volume"
Alan Couzens@Alan_Couzens
Say it with me... No matter how much you want it to be true.. Intensity is not a substitute for volume. If you really want to be fit, you have to put in the time.

It is my birthday today, so I allowed myself a completely self‑indulgent data analysis.
I have had the “what is the hardest endurance sport” argument in so many changing rooms and cafes that I lost count years ago. Swimming feels psychologically hardest for me. Cycling feels highest risk. Running just feels brutally honest.
So this time I tried to answer it with data.
I pulled nearly a million sessions across nine endurance sports and looked at what each one does to the cardiovascular system, both per minute and per session.
Here is what I found:
- Every sport has a distinct heart‑rate “fingerprint”. Running is a tight, right‑shifted bell around 145 bpm. Walking and ski touring sit broader and lower. Downhill skiing is all peaks and troughs.
- Running really is hard on the heart. It has the highest session average, peak HR, and sustained intensity ratio.
- Walking’s “high” intensity ratio is a statistical trick. Low average, low peak, very flat sessions that only look hard on paper.
- Downhill skiing has the biggest swings. Peaks rival outdoor cycling, but average HR sits near walking. That 47 bpm gap matches the feeling of short bursts and a lot of standing around.
- Cross‑country skiing behaves like running at the top end and like cycling on average. Huge peaks, long gliding recoveries.
- Indoor cycling is the purest steady effort after running. The sustained profile is similar in relative terms, but the absolute load is lower because seated cycling simply costs less than weight‑bearing running.
Within the same person, running still wins. Among 1,480 people who both run and ride outside, 93% hit a higher fraction of their personal max HR when they run. Same body, same heart, different biomechanical demand.
Then I changed the question. Because intensity is only part of the story and I recently cycled for 35 hours at a low Heart Rate, but it certainly felt pretty hard!
Do you want to reward time on feet, or time in the red zone?

Tennis players live 9.7 years longer than sedentary people.
Not 9.7 months. 9.7 years. Nearly a decade.
The Copenhagen City Heart Study tracked 8,577 people for 25 years and ranked every sport by how much life it adds.
Badminton: 6.2 years. Soccer: 4.7. Cycling: 3.7. Swimming: 3.4. Jogging: 3.2.
Tennis almost triples jogging.
A separate study of 80,000 adults found racket sports cut all-cause mortality by 47% and cardiovascular death by 56%. Swimming hit 41%. Aerobics hit 36%.
The question is why racket sports destroy everything else.
Three mechanisms stack on top of each other.
First, the physical demands. A tennis rally requires explosive sprints, lateral cuts, and sustained aerobic output. You're training fast-twitch and slow-twitch muscle fibers simultaneously. Most cardio only trains one system.
Second, the cognitive load. You're reading spin, predicting angles, adjusting position, and executing motor patterns in real-time. Your brain is solving spatial puzzles at 80+ mph. That hand-eye coordination and strategic processing builds neural connections that protect against cognitive decline.
Third, and this is the one researchers keep coming back to: you literally cannot play alone. Every racket sport requires another person on the other side of the net. That forced social interaction triggers neurochemical benefits that solitary exercise cannot replicate. Strong social connection alone increases your chance of longevity by 50%.
Jogging is you and your thoughts. Tennis is you, a strategic opponent, and a community.
Dr. Daniel Amen is right. The data is overwhelming. If you want the single highest-ROI activity for a longer life, pick up a racket.

A global trend like this will never happen again - it was the closest we got to world peace. 🫰
In 2013, the internet witnessed one of the first truly global sensations of the social media era: the Harlem Shake. Fueled by American producer Baauer’s track, the meme exploded, with thousands of versions surfacing within days and millions of people around the world joining in.
The format was simple and repetitive, making it perfect for virality. The video would begin with a lone person dancing awkwardly, followed by a sudden “drop” in the music. The screen would then cut abruptly, revealing a chaotic scene where everyone in the frame was in costume, making wild movements, with no rhyme or reason. This easy-to-replicate structure encouraged schools, businesses, the military, universities, and even government agencies to create their own versions.
Unlike scripted campaigns, the Harlem Shake spread organically, illustrating the power of collective participation in online culture.

@Math_files It cannot be understated how much the desire to do less work has advanced us as a species
