Adherence

High-intensity functional training (HIFT) is a time-efficient exercise modality that elicits positive affect and improves fitness and glucose metabolism in individuals with metabolic syndrome, potentially mitigating barriers to exercise adherence such as lack of enjoyment and time constraints.

If you struggle with sticking to an exercise routine because you feel you don't have time or you find it boring, try High-Intensity Functional Training (HIFT). It involves short, intense workouts (under an hour) using bodyweight and simple equipment, often in a group setting. This approach is designed to be more enjoyable and time-efficient, which may help you stick with it longer and improve your metabolic health markers like blood sugar and lipids.
