Short on time but ready to torch fat and boost fitness? This 15-minute full-body HIIT (High-Intensity Interval Training) workout is scientifically proven to maximize calorie burn, rev up your metabolism, and deliver real results—in less time than it takes to brew coffee.
HIIT alternates short bursts of all-out effort with brief recovery periods, keeping your heart rate elevated and triggering the “afterburn effect” (EPOC), where your body continues to burn calories even after the workout ends.
No equipment? No problem. This routine uses just your body weight and can be done anywhere—home, hotel, park, or gym
1. Sumo Explosive Squats
Imagine you’re a sumo wrestler, placing your feet shoulder-width apart and facing outward. With your torso straight, push yourself with your feet facing outward. You have to push with your quadriceps and then jump. As mentioned above, perform up to 12 repetitions.
2. T-Plank
Position your body as if doing push-ups on the floor. Place your toes on the floor and your wrists flexed below your shoulders. Extend your right arm parallel to the floor and let it hang in the air for about 10 seconds. Concentrate on the upper back muscles. Repeat the same movement with your left arm. Note that both movements are 1 repetition. In this case, you only need to do a total of 3 repetitions.
3. Opposite Shoulder Push-Up
As if doing push-ups with your arms stretched out, lower your chest for 3 seconds and quickly come back up. As you come up, touch your right hand to your left shoulder. Then lower your chest again as if you were doing a normal push-up. Do the same with your right hand touching your left shoulder. Perform 12 repetitions.
4. Power Thrust
Get into position by squatting and placing your hands on the floor under your shoulders. Then jump your feet back and stand as if doing push-ups. Return to the same position as before and jump up, extending your hands to place yourself on the floor and return to the starting position. Repeat for 12 repetitions.
5. Lateral Lunge
In a semi-squat position and slightly bent over, make an explosive jump up and to the right. Land softly on the floor and repeat the same movement to the left. As in the previous exercise, both movements are 1 rep. Perform a total of 12 repetitions.
6. Mountain climber
Place your elbows under your shoulders like a plank and flex your toes. Shrug your hips and bring your right knee forward. Return to starting position and repeat with left knee. Both movements count as 1 repetition, so do the same until you reach 12 repetitions.
7. Tuck Jump
Stand with heels shoulder-width apart and feet slightly outward. Half-bend your knees and place your arms across your chest or outward. Your hips should be behind you as you lower into the squat. Once in position, jump up as high as you can, bending your knees toward your chest and bringing your heels toward your buttocks. Land gently on the floor and repeat until you have completed all 12 repetitions.
