Love the fast results of high-intensity interval training (HIIT) but really into the muscle-toning of Pilates? You're in for a treat. Cassey Ho, creator of Blogilates, recently introduced a new program that helps you get a healthy body in the comfort of your own home.

PIIT28, a fun fusion of Pilates and HIIT exercises, requires nothing but your shoes and a yoga mat. And the best part? It's only 28 minutes and 40 seconds of your day. Don't be fooled, though — even though it's short, you'll definitely work up a sweat.

Through the 28-day program, people haven't just slimmed down, but more importantly, found strength and confidence through the workout.

"You feel invincible and powerful. Yes, people want to lose weight, but that can't be your main focus. Your focus should be to get stronger and to have fun while you're doing it," Ho says. "If you stick with those two things, you're more likely to stick with your routine. That's going to be the gold right there. Your body will really start changing."

The program itself costs less than most monthly gym memberships at $40, but you can try out some of the moves for free below.

"Anyone can squeeze in this workout, whether you're a mom at home with your kids or just don't want to waste time going to and from the gym," she says.

1. Mountain Climbers

How It's Done: Begin in a full plank. Exhale, and pull your right knee in toward your hands. Inhale, and extend the leg back to plank. Repeat alternating sides and climbing as fast as you can.

Modification: Either bring your knees into your chest at a slower pace, or drop to a plank on your knees and bring them into your chest slowly, one at a time.

2. Criss-Cross

How It's Done: Lie on your back with your legs in tabletop and your hands behind the nape of your neck, elbows wide. Exhale, then lift the right shoulder off the mat and bring it toward the left knee. Inhale, return to start, and alternate to the other side.

Modification: Keep your head, neck, and shoulders on the mat, and only perform the exercise with the legs.

3. Wide High Knees

How It's Done: Standing tall, feet wider than hip distance apart, jump from one foot while bringing your opposite knee up as high as possible. Next, jump with the other foot and repeat.

Modification: Omit the jump and simply bring one knee up as high as possible while alternating legs.

4. Triple Crunch

How It's Done: Lie on your back with your feet on the mat, knees bent. Place your hands behind the nape of the neck with the elbows out wide. Next, brace your abdominals as you lift the shoulders off the mat for three counts. Every time you crunch up, lift a little higher for a total of three crunches before returning to start.

5. Plank Jacks

Modification: Omit the jump and step one foot to the outside of your mat at a time.
