Opting for cardio during your 30 minutes can really maximize your time. "Cardio is always hard, but it is especially important as we age," says Liv Lo Golding, founder and CEO of FitSphere. "Cardiovascular exercise is directly related to how hard your heart is working, and it can cause us to breathe heavy, sweat a lot, and feel uncomfortable, especially if we are not used to it." Plus, there are so many benefits to cardio workouts in addition to strengthening your heart rate. Joi says they can help you sleep better, make your body more mobile, and burn calories.
Personally, I used to think of cardio as running, and that always turned me off because I don't consider myself a big runner. But both Golding and Joi say that it's more than just a long run. You can incorporate cardio moves into other workouts like HIRT (high-intensity resistance training), break up a long run with sprints, go on a hike, or even dance it out.
The best part of cardio is that it's great for all levels. "Nearly every type of cardio workout can be modified for all levels—for example, a long walk versus a power walk versus a hike. They all are walking but focus on different things, like elevating the heart rate and maintaining a casual pace versus intervals of intense speed walking versus steadily paced intervals of harder effort on a hill or mountain," explains Rebecca Kennedy, Peloton instructor. "Cardio workouts can improve your mood, your heart health, boost your confidence, increase your endurance, provide an immediate caloric output, and be an incredible mental and emotional release."
