This is a great way to get your heart rate up and burn calories. Perform jumping jacks for a few minutes to warm up.
Stand in place and lift your knees as high as possible while jogging in place. Engage your core throughout the exercise.
Start in a plank position and alternate bringing your knees toward your chest as if you're climbing a mountain. This is an excellent full-body exercise that targets the core.
The basic plank is highly effective for engaging your entire core. Hold a plank position on your elbows and toes for as long as you can, and gradually increase the duration.
Lie on your side and lift your body onto your elbow and feet. Hold the side plank position on each side to work your obliques.
Burpees combine cardio and strength training. Start by standing, then drop into a squat, kick your feet back into a plank, return to the squat position, and jump up explosively. Repeat in a fluid motion.
Sit on the floor, bend your knees, and lean back slightly. Hold a weight or a household item like a heavy book, and twist your torso to the left and right, engaging your obliques.
Lie on your back, lift your legs off the ground, and bring your right elbow towards your left knee while extending your right leg out. Alternate sides in a pedaling motion to engage the obliques and rectus abdominis.
