Researchers present new findings on mental fatigue, mental training, and the importance of your surroundings

They don’t necessarily save energy, but a new study suggests they might save your legs

To optimize your health or supercharge your training, you sometimes need to look beyond the lab

There are both healthy and harmful ways to get away from it all, psychologists point out

Researchers look back on the lessons from 25 years of “live high, train low.”

First there was altitude training. Then it was heat training. Now it’s… pollution training?

Plyometrics can make you a more efficient runner, and it turns out they don’t need to be complicated or risky

New data finds that endurance- or speed-oriented muscle fibers don’t determine how you respond to strength training

So-called “augmented feedback” can offer both information and motivation. A new study tries to separate the effects.

Age may be just a number—but so is your weekly mileage.

Double threshold days and lactate meters have propelled Jakob Ingebrigtsen and others to the top. Should the rest of us follow suit?

The real magic of much-hyped ketone supplements, according to Belgian scientists, is how they enhance recovery

The algorithms used to estimate your training load have some fundamental flaws, scientists say.

Runners smack the ground harder—but get injured less—in more cushioned shoes. New research explains why.

Recovery, just like training, is highly individualized from person to person. Recent research shines a light on why that is.

Different workout styles can get you equally fit, but they affect your body differently—which suggests that you should mix it up.
