[–><!–>High-intensity interval training is one of the best ways to pack a lot of exercise into a short period of time. HIIT workouts are so efficient because they alternate short bursts of very intense exercise with even shorter rests. That constant game of catch-up leads to quick cardio gains. –><!–>

[–><!–>Here is your workout! Take a few minutes for a dynamic warm-up before you start. Once you’re ready, click the button below to start the timer. Remember: Intensity is the key to HIIT, so be ready to push yourself. But if you experience dizziness, unusual heart rhythms or any sharp pain, stop. If you can’t go all out the first time, don’t get discouraged. The more HIIT workouts you do, the stronger you’ll feel. Enjoy!–><!–>
