Regular high-intensity interval training (HIIT) exercises such as squats, sprints, and pedalling can improve the treatment of non-alcoholic fatty liver disease by impacting on several metabolic pathways in the body, finds a new study.

A team from the University of Eastern Finland found that regular HIIT exercise over a period of 12 weeks significantly decreased the study participants' fasting glucose and waist circumference, and improved their maximum oxygen consumption rate and maximum achieved workload.
