“The harder you work right now, the faster your body’s going to change,” says Jillian Michaels in her brand new, game-changing Seven-Minute, Seven-Day Workout Challenge, designed for Yahoo Life readers. The iconic trainer created the program to suit busy people of all fitness levels, with an exclusive reward for you, too!

Day two’s workout (Catch Day one, here) is all about High-Intensity Interval Training, otherwise known as HIIT. HIIT workouts are major fat-burners, because they require you to exert yourself to the max for short intervals—sort of like a series of sprints instead of a marathon. Putting intense stress on your body for brief spurts followed by brief recovery periods forces your system to adapt fast and turbo charges its calorie-burning powers.

You don’t just burn calories during this HIIT challenge—your body continues to melt fat long after it’s over. “I know it can sound a little intimidating,” says Michaels, “but I promise you we’re going to cruise right though this, and you’re going to feel amazing.”

Oh, and that reward?

This body-carving challenge is just the beginning. Michael’s is offering Yahoo Life readers an exclusive deal on her fitness app, which is stocked with a slew of effective 7-day workouts, and much more. Enjoy a free 7-day trial and a 3-month subscription for just $19.99 (usual price is $44.97), and 12-months for $59.99 (usual price is $179.88).

Ever marvel at the chiseled physiques of professional boxers? Speed bag training is one of the main tools in their fitness arsenal. Punching at an invisible speed bag per Michaels’ coaching burns an incredible amount of calories while also engaging your shoulders and biceps and targeting soft, flabby upper arms. “I get it. In the moment, sometimes exercise is not fun,” Michaels says. “But the results? That’s what you’re fighting for.”

Bolster bone density and get your heart pumping with Speed Rope

One of the most simple ways to boost your heart rate and metabolism is with a good old-fashioned jump rope—an athlete favorite. And with Michaels’ Speed Rope challenge, you don’t even need a rope! For 20 seconds, “synergize your upper and lower body as if you’re really jumping rope,” says Michaels, “and focus on your breathing. This exercise should be done fast and with your feet just barely coming off the ground. It not only burns fat but improves coordination, helps bone density, and strengthens your legs.
