The Fat-Burning HIIT Circuit
- Jumping Jacks Full body cardio starter. Jump feet out while raising arms overhead, then jump back in. Move as fast as possible.
- Squats Lower down like you’re sitting in a chair, then explode back up. Keep your chest lifted and core tight.
- Mountain Climbers In high plank position, quickly drive your knees toward your chest one at a time. Keep your hips low.
- Push-Ups (Knee or Full) Lower your chest toward the floor, then push back up. Modify on knees if needed. This builds upper body strength.
- High Knees Run in place, driving your knees up toward your chest as high as possible. Stay light on your feet.
- Bicycle Crunches Lie on your back, hands behind head. Bring opposite elbow to knee while extending the other leg. Twist fully.
- Glute Bridges Lie on your back, knees bent. Lift your hips high and squeeze your glutes at the top, then lower slowly.
- Burpees (Finisher) Squat down, kick feet back to plank, jump feet forward, and stand up with a jump (step back if needed).
Pro Tips for Maximum Fat Burn
- Push yourself during the 40-second work intervals — this is where the magic happens.
- Focus on form first, especially during push-ups and burpees.
- Breathe properly: Exhale during effort.
- Do this workout in the morning on an empty stomach for even better fat-burning results (optional).
- After finishing, do 5–8 rounds of Stomach Vacuums to tighten your waist.

Nutrition Tip for Faster Results
Pair this HIIT with a moderate calorie deficit and high-protein meals. Protein helps preserve muscle while you burn fat.
