I incorporate HIIT into my fitness routine by mixing it with other workouts to keep things balanced. I usually do HIIT two to three times a week, alternating between high-intensity intervals and rest periods. I choose a mix of exercises to target different muscle groups, like sprints, jumping jacks, or bodyweight exercises. I make sure to warm up properly before starting and cool down afterward to prevent injuries. By varying the intensity and types of exercises, I stay motivated and continually challenge myself.
