The most effective way to reduce visceral fat is a combination of high-intensity interval training (HIIT) and resistance training, though regular moderate-intensity cardio or aerobic exercise also helps, according to current research.In this episode of the “NASM CPT Podcast,” host Rick Richey unpacks the scientific evidence on exercise strategies for reducing visceral fat, addressing frequent confusion over whether HIIT or continuous moderate-intensity exercise is better.
Citing several systematic reviews and meta-analyses, Rick explains that while some studies show no clear advantage between HIIT and steady-state cardio, many find that interval training, especially when extended beyond 12 weeks, provides superior reductions in visceral fat, particularly for individuals with overweight or obesity. He also highlights that progressive, combined training—mixing vigorous-intensity cardio with moderate or low-intensity resistance training—can further support visceral fat loss, which is particularly beneficial for at-risk groups such as older adults and postmenopausal women.
Listeners will learn how to apply these research-backed exercise protocols for themselves or their clients, how to track progress, and why gradual progression is key, especially for those new to higher intensity workouts. This presentation also offers practical coaching insights on how to encourage clients to embrace challenging new routines.
