(CNN)During the holidays, people are much more prone to sedentary behavior -- like eating, sleeping or watching TV -- to manage their stress, according to research. To counteract all that feasting and couch potato inactivity, many of us know that regular aerobic exercise, like running or going for a walk, is ultimately more effective at reducing stress.

What happens, though, if you've been displaced -- stuck in your own small living quarters by yourself or watching over loved ones? The US Centers for Disease Control and Prevention on Monday urged Americans not to travel for the upcoming holidays, so these scenarios could very well be likely this season as the Covid-19 pandemic continues to surge. How, then, can you fit in exercise, especially as the weather gets colder and snowier?
If you're short on space, time and equipment, I've devised a full-body workout that you can do in any corner of any room.
The moves include body-weight exercise paired with cardio for a complete high-intensity interval training, or HIIT, workout. I chose a combination of lower-body strength training and upper-body exercises that don't require any equipment. What's more, to work your core, I've included standing abdominal exercises -- so you don't even need a mat.
As we ramp up to the holidays, fitting in this routine will leave you feeling more energized and give you a boost of feel-good hormones. These movements will improve your circulation, digestion and even help speed up your metabolism after eating all of your holiday favorites.

High knees

This exercise loosens up the hips and gets your heart rate up.
Standing with your feet as wide as your hips, lift up the right knee toward your chest and then lower the leg. Next lift up the left knee toward your chest. Alternate these high-knee moves; you can keep this as a low-impact exercise by simply marching in place with your arms at your sides.

Side crunch in a sumo squat

This exercise builds lower body strength in the glutes, hamstrings and quads while working the core. Specifically, you'll be engaging the sides of the waist and working on the love handles.
Stand with your feet as wide as your hips and then turn your toes out. Place your hands behind your head. Bend the knees and sit back into a squat with the feet and knees turned out.

Repeat 10 times.

Ballet plié with arm raise

This exercise works the stabilizing muscles of the core as well as the inner thighs and shoulders.
