If you’re short on time but want maximum results, this cardio HIIT core workout delivers exactly that. From the first round to the final plank, this workout is designed to elevate your heart rate, challenge your strength, and fire up your core — all in a structure that feels doable and empowering.
Rather than long, drawn-out sessions, this workout uses short intervals and purposeful movement to help you build endurance, improve coordination, and strengthen the muscles that support everyday life. Even better, it’s efficient, repeatable, and ideal for busy schedules.

Round 1: Build Rhythm and Warm the Body
The first round raises your heart rate while activating your legs and core.
Round 1 Exercises
👟 Heel Skips

Round 2 Exercises
↔️ Lateral Shuffle Twist

The Mayo Clinic explains that regular aerobic exercise supports heart health, improves endurance, and strengthens the cardiovascular system — even when workouts are shorter and performed consistently. In their overview of aerobic exercise, they highlight how activities that raise your heart rate help improve circulation, boost stamina, and support long-term heart health.
That’s exactly why workouts like this cardio HIIT core workout are so effective. Short, structured sessions make it easier to stay consistent while still supporting cardiovascular fitness and overall wellness.
