Slept 8 Hours and Still Tired? Look at What Happened Before Bed

by Arnold | Oct 20, 2026 | Lifestyle, Sleep

You were in bed by ten, you got up at six, and your watch still gives you 58 points and a heart rate that stayed high half the night. Eight hours in bed and you feel like you slept four, the classic case of 8 hours of sleep but still tired, so you start blaming your...

Why You’re Tired When Your Training Hasn’t Changed

by Arnold | Oct 13, 2026 | Training, Sleep

Nothing in the plan has changed, same easy rides and same two harder sessions as last month, but your legs feel heavy on the stairs, the easy pace suddenly costs something, and it takes you half an hour to get out of bed. The training log has no answer, so you blame...

“I Think I’m Overtrained”

by Arnold | Oct 7, 2026 | Sleep, Training

“I think I’m overtrained.” Every now and then an athlete says it to me, and I take it seriously, even when it’s far more likely to be mild overreaching. The terms overreaching and overtraining get mixed up easily, but the signs underneath are...

What I Gave Up to Train More

by Arnold | Sep 30, 2026 | Lifestyle, Training

People often ask me how to find time to train as much as I do. The honest answer starts in an office a few years ago, where I was the Hungarian country manager for a sports retailer and, by coincidence, most of our marketing team were runners. The same hobby at very...

Why Volume or Intensity Is the Wrong Question

by Arnold | Sep 23, 2026 | Training

People ask me fairly often whether they should train more or train harder. It’s the old volume or intensity question, and when I hear it, I usually think of one cyclist I train. He has barely done an extreme workout in his life. He rarely rides longer than three...

Which Sport Costs You the Most Recovery

by Arnold | Sep 17, 2026 | Health, Lifestyle, Training

You have maybe four hours this week. Three sessions, four if Saturday cooperates. Nobody tells you which of them will still be sitting on you on Thursday. Most training advice counts hours, as if an hour is an hour. It isn’t. The same hour costs you very...

Nutrition for Endurance Training: What Actually Sticks

by Arnold | Sep 12, 2026 | Health, Sleep, Training

I don’t think there is one best diet. Anyone who tells you there is probably has something to sell you. What interests me more is which rules actually survive real life. Most diets don’t fail because the idea was wrong. They fail because people can follow...

Ironman Training and Sleep: What 20+ Hours Taught Me

by Arnold | Sep 9, 2026 | Sleep, Health, Training

“Are you an Ironman?” I’ve been asked some version of this question for a decade, whenever someone finds out I race multisport. No, I always say. I race quadrathlon mainly — triathlon with a kayak leg added — and for training and preparation, some...

Do Ice Baths Actually Work? What I Found

by Arnold | Sep 6, 2026 | Lifestyle, Health, Training

I’ve tried ice baths in a few different forms. Before or after a sauna, and the more natural version too, swimming in a frozen river in winter. I know the feeling pretty well by now, and I don’t like it. That’s really where this started. It...

Heat Dome Sleep Disruption: My Actual Fix

by Arnold | Sep 3, 2026 | Sleep, Health

Most people would assume shorter days are the hard part of the year for sleep. This year, for me, it was the opposite. Summer was the season that actually broke things — heat dome sleep disruption, mostly, and everything I had to do about it. What Summer Actually Cost...
