High Intensity Training and Appetite Suppression

Vigorous exercise suppresses hunger more than moderate exercise for healthy adult men and women, according to a small study described in Journal of the Endocrine Society (2024). Among a group…

Longer Sprint Intervals Achieve Fitness Faster
Longer Sprint Intervals Achieve Fitness Faster

Comparison of different sprint interval protocols shows most efficient ways to exercise. New research shows that repeating multiple short sprint intervals is not as beneficial as fewer longer sprint intervals,…

High-intensity training
Build Up to High-Intensity Training

In light of increased participation in high-intensity training and increased rates of heart attack and sudden cardiac death among male marathon participants, the American Heart Association has issued a scientific statement to outline the benefits and risks of vigorous exercise programs.

HIIT Intervals
60-Second HIIT Beats 30-Second HIIT

Research shows that when recovery breaks during high-intensity interval training are too long, they undermine the effectiveness of the training.

ReHIT training
Is REHIT Training Effective?

REHIT is a new training approach influenced by high-intensity interval training (HIIT), particularly its time-saving aspect. While a typical HIIT program lasts 30 minutes, a REHIT session consists of two or three 10- to 20- second sprints, separated by up to 3 minutes of recovery, in a 10-minute cardio session. Some experts believe this reduced-exertion approach may attract people who are inactive, have a chronic disease or simply lack time.

HIIT and Weight Training Sequence
HIIT or CWT: Does Sequence Matter?

A new study, conducted under the leadership of IDEA author and presenter Len Kravitz, PhD, compared cardiovascular and metabolic responses to two exercise protocols: (1) six bouts of high-intensity interval training (HIIT) followed by three rounds of circuit weight training (CWT) and (2) CWT rounds interspersed with HIIT bouts. Fourteen trained young men (ages 25.7 ± 4.4) participated in the study, completing each of the two programs 3 days apart.
