4. 10-Minute HIIT
High intensity interval training was meant for time crunched workout days. Try this 10-minute calorie sizzler anytime, anywhere (it’s perfect for hotel rooms!) you need a quick shot of cardio.
Ski moguls: Stand with feet together, squat down, and swing arms behind you. Jump up and to the right, swinging arms in front of you, landing in your start position. Continue jumping side to side as quickly as you can.
Squat jumps in and out: Stand with feet together. Lower into a squat and swing arms back behind you, and then quickly jump up, swinging arms overhead. Land in a squat position with feet hip-width apart, and swing your arms back to immediately jump up again. Repeat as quickly as you can, jumping in and out with your feet each time.
Scissor skier: Stand tall with feet together, arms by sides. Jump up and bring left foot forward and right foot back as you reach right arm up and left arm back (palms facing in). Land softly and then immediately jump again, switching feet and arms in a scissor motion as quickly as possible.
Plank side tucks: Start in straight-arm plank position with feet together. Jump both feet in, tucking knees towards the outside of left elbow. Jump feet back to full plank, and then quickly repeat on the other side. That's one rep. Repeat as quickly as you can, alternating sides each time.
Side-to-side shuffle jumps: Stand with feet hip-width apart, squat down, and reach right hand to the floor, just outside of right foot. Push off both legs and jump up and to the left, landing in a squat, reaching left hand to the outside of left foot. Repeat as quickly as possible, moving from side to side.
Squat jacks: Lower into a squat and bring arms in front of you. Jump feet together, still holding squat position, as you swing arms back by sides, keeping elbows bent. "Jack" feet out and in as quickly as you can without coming up out of your squat.
Donkey kick ups: Stand with feet hip-width apart, arms by sides. Push hips back and bend knees to lower into a squat and prepare for a donkey kick, placing hands under shoulders, keeping arms straight. Shift weight into arms and jump up with legs, kicking heels in close to butt. Land with feet hip width and jump straight up, pushing arms behind body as you jump. Land and immediately repeat.
