To speed up your metabolism, your workouts must strengthen your muscles while spiking your heart rate—and of course, you need to do them regularly. These routines don’t have to last long: in fact, studies have shown that high-intensity interval training (HIIT) is super-effective at burning belly fat by pushing your body to its limits through short bursts of all-out energy.
This 10-move HIIT sequence gives you a full metabolic workout in just under 10 minutes. Rather than use dumbbells, start each exercise from plank position, so you work with your own bodyweight to get lean. You’ll fire up your chest and core, increase shoulder stability and hip mobility, and tone your butt and legs. That’s a lot of rewards for minimal time commitment!
Repeat each of the following exercises continuously for 40 seconds, taking 20 seconds of rest as you transition between them. Perform this workout three days a week for eight weeks to see results.
Exercise 1: Charleston
Beginning in proper plank position, step one foot forward between your hands and power through that knee to lift the other leg up. Return to plank; repeat on the other side.
Note: To make this move more challenging you can hop off your planted foot as you lift the opposite leg.
Switch it up with these plank variations for your next core workout.
Exercise 2: Thread the Needle
From plank, weave one leg long beneath your body and touch it with the opposite hand. Return to plank; repeat on the other side.
Exercise 3: Pop Jack
From plank, jump both legs forward into a wide sumo squat with toes pointed outward. (Here’s how to do squats and lunges without killing your knees!) Place your hands in front of your chest, as if ready to catch a ball. Return to plank and repeat.
Exercise 4: Push-Up Side-to-Side
From plank, bring your right arm and right leg further out to the side, then do one push-up (drop to your knees, if necessary). Return to plank; repeat on the left.

From plank, jump both feet outside of your right hand. Return to plank. Jump both feet outside of your left hand. Repeat.
