Cardio was the first thing I tried when I started this whole process, and I made plenty of mistakes chasing calorie burn instead of building a habit. Based on my research, the type of cardio matters less than whether you’ll keep doing it.
That’s the whole idea behind this 20 minute cardio workout at home. No equipment, no commute, and a low impact version for the days your knees, or your downstairs neighbors, need it quiet.
How the Workout Works
It’s a circuit. You do each move for 40 seconds, rest for 20 seconds, then go straight to the next one. Five moves make a round, and you do three rounds back to back.
- Warm-up: 3 minutes
- Circuit: 3 rounds of 5 moves, 15 minutes
- Cool-down: 2 minutes
Work hard enough that talking in full sentences is difficult by the end of each round, but not so hard that your form falls apart.
Warm-Up (3 Minutes)
- March in place, swinging your arms, 1 minute
- Arm circles and shoulder rolls, 30 seconds
- Slow bodyweight squats, 30 seconds
- Alternating step-back lunges, 1 minute
The Standard Circuit
- Jumping jacks. Land softly on the balls of your feet with your knees slightly bent. Brace your core so your lower back doesn’t arch.
- Squat to reach. Feet shoulder-width apart, sit your hips back, then stand and reach both arms overhead. Push through your whole foot, not just your toes.
- Mountain climbers. Start in a high plank position with your hands under your shoulders. Drive one knee toward your chest at a time, and keep your hips level with your shoulders instead of hiking them up.
- Skaters. Hop or step side to side, landing on one leg with a soft knee while the other leg reaches behind you.
- Standing punches. Soft knees, tight core, fast alternating punches straight out in front. Rotate slightly through your torso instead of just swinging your arms.
The Low Impact Version (No Jumping)
Same timing, same structure, and one foot always stays on the floor. It’s still real cardio. Low impact means easier on your joints, not easy.
- Step jacks. Step one foot out to the side as your arms go overhead, then bring it back. Alternate sides quickly.
- Squat to reach. Same as above, just faster.
- Standing knee drives. Pull one knee up toward your chest as you pull your hands down, then switch legs. For more core work, do slow mountain climbers with your hands on a sturdy chair or counter.
- Side steps with a toe tap. Step wide to one side, tap the other foot in, then go back the other way.
- Standing punches. Already low impact. Speed is what makes them cardio.
Cool-Down (2 Minutes)
- Walk in place, slowing down, 1 minute
- Standing quad stretch, 15 seconds per leg
- Hamstring stretch or forward fold, 30 seconds
How Often to Do It
Three times a week is a good starting point, with a rest day or a walk in between. If weight loss is your goal, pair it with two strength workouts a week and a moderate calorie deficit. Cardio helps, but strength training protects the muscle that keeps your metabolism up after 40. My strength training guide for women over 40 covers that side, and the at-home circuit workout plan puts both into a four-week schedule.
Once three rounds feel manageable, add a fourth round, or change the timing to 45 seconds of work and 15 seconds of rest.
On days you feel run down, do the low impact version for two rounds instead of skipping the session. Keeping the appointment with yourself matters more than how hard any single workout is, and a short session still counts toward the habit you’re building.
Other Cardio Options That Work
If circuits aren’t for you, these burn calories just as well when you do them consistently:
- Walking is the most underrated option and the easiest to keep doing. See my walking for weight loss page.
- HIIT packs more intensity into less time, but it needs more recovery after 40. I cover how to do it safely in HIIT for women over 40.
- Cycling, swimming and rowing are all low impact and great if you have the equipment or a pool.
- Dancing counts. If it gets your heart rate up and you enjoy it, it’s cardio.
Tips to Get the Most Out of It
- Wear supportive shoes, even at home. Bare feet on hard floors are tough on your feet and ankles.
- Put a mat or rug down for the moves that start from a plank position.
- Keep water nearby and drink between rounds.
- Track something simple, like rounds finished or how you felt, so you can see your performance improve.
Frequently Asked Questions
Is a 20 minute cardio workout enough to lose weight?
It can be, as part of a plan. Three 20-minute sessions a week plus daily walking and a calorie deficit is a realistic setup. The workout alone won’t outrun your diet.
How many calories does a 20 minute cardio workout burn?
Roughly 150 to 250 for most women, depending on your weight and how hard you work. Treat fitness tracker numbers as estimates.
Can I do this workout every day?
The low impact version, yes, if you feel recovered. For the standard version, give yourself at least one easier day between sessions so your joints can recover.
This is not medical advice. If you have heart, joint or balance problems, talk to your doctor before starting a new exercise routine.
