Eight weeks of HIIT increases both the number and efficiency of muscle mitochondria by expanding their energy-producing inner membranes.

We all know that person – or perhaps we are that person: the high performer who dominates a jam-packed day of back-to-back meetings and strategic calls, and then, without missing a beat, heads ...

Researchers from the University of Southern Denmark investigated how eight weeks of high-intensity interval training affect the structure of mitochondria—the parts of muscle cells that produce energy.

A new study suggests that HIIT workouts may help preserve lean mass in older adults compared to moderate exercise—but changes were small. Here's what to know.

Older adults may not be thinking about high-intensity interval training (HIIT) when they think about their brain health, but a study published Feb. 17 in NPJ Science of Learning found it can improve ...

A single session of high-intensity exercise can disturb the body's main stress hormone, leading to less activity after the workout, a lower body temperature, and weight gain, a new study of mice finds ...

A small study has found that combining time-restricted eating and high intensity exercise may improve cardiometabolic health and contribute to weight loss. Participants who combined this diet and ...

You’ve probably heard of high intensity interval training (a.k.a. HIIT), but have you heard of high impact training? Though they sound similar, these two types of exercise are a little different. Like ...
