How to Choose the Best Cardio Machine for Yourself

buyers guide image

Besides your budget and the available space, here’s what you need to consider before deciding which cardio machines may be most effective for you.

Your Training Goals, Style, and Intensity You Prefer

Doing a High-Intensity Interval Training (HIIT) on a treadmill may be the most effective for people who are training for weight loss or a race, striving to improve their performance, and increase endurance.

Maybe you are doing CrossFit, if so, we have a buyer's guide on the best CrossFit equipment.

“The first step in identifying the best cardio machine is to get clear on your goals.


Are you training for performance; want to run a marathon or compete in a fitness competition? Are you training for health benefits; do you need to lower your blood pressure or get your diabetes under control? Are your goals more aesthetic; do you just want to feel confident in your two-piece at the pool this summer?


How you answer those questions would determine the best cardio machine for you.”


- Rachel Southard, Director of Personal Training Operations for Anytime Fitness

Here are some guidelines on which equipment to choose:


Those who struggle with balance but would like a low-impact, full-body workout may choose a safer option with minimal impact on joints (ankles, knees, and hips) - the elliptical machine, which also allows you to engage core muscles by pushing and pulling the handles.

We did a list of the best compact elliptical machines, if you are low on space.

Stationary Bike

People aiming at intense workouts for fat and calorie burn, but with the spine, and other upper or lower body problems, may opt for a stationary bike.

Experts advise alternating your workouts with sprint cycling intervals and distance rides if practicing for a cycling competition or aiming at improving your overall performance.

If you like the sound of a stationary bike, you should check out the MYX Fitness Bike by MYXfitness.

They have combined a Star Trac Bike with a sleek and interactive touchscreen tablet. It comes with a built-in heart rate monitor to track the intensity of your workout, and it is compatible with the Apple watch.

This stationary bike is reliable, durable, and it is great for burning calories and fat.

What we found impressive about the MYX system was the fact it is updated weekly with thousands of free workout videos. These videos are often led by world-class trainers for more than just cardio.

The MYX membership comes at a separate monthly price. However, with the amount of content added weekly, it seems worth the price.

Stair Climber/ Stepmill

Stair Climber

If you want cardio equipment that’ll tone your lower body, providing resistance and strength training, a piece of equipment like a stair climber/stepmill may be great.

The stepping motion and stair climbing movement pattern can help strengthen your legs, build endurance, and lose weight.

Rowing Machine / Ergometer

If you know how to use it properly, a rowing machine/erg (ergometer) may also be fantastic for enhancing your endurance and stamina.

You can check out our article on the best budget rowing machines.

It’s perfect for those who want the effective low-impact (an)aerobic exercise easy on their joints to let their muscles recover from previous vigorous workouts and reduce the risk of injury while avoiding to hinder their progress.


Studies show that the treadmill is the optimal indoor exercise machine for enhancing energy expenditure when compared to the stair stepper, cross-country-skiing simulator, Airdyne, cycle, and rowing ergometer. [2]

Another study also indicates that the treadmill, rowing erg, and ski simulator cause increased energy expenditure more than the health rider and cycle ergometer. [3]

Your training goals will probably change over time, and your body quickly adapts, so mixing up all these fitness machines may be the most advantageous approach to cardio workouts.

The Muscle Groups You Want to Target

Instead of overusing the same muscle groups, to keep injuries at bay, make sure you stretch and mix up different cardio equipment because cross-training helps build and strengthen the small muscles that support the commonly fatigued major muscles.

A good way of stretching is just hanging on a pull-up bar. You can check our buyer's guide on the best overall standing pull-up bars.



For instance, if your workout plan includes toning and sculpting your gluteus maximus, or flexing out your quads and hamstrings while burning calories and improving your cardiovascular health, climbing stairs may yield fantastic results [4], so it would be wise to use an indoor stepper or stair climber.

Hips and legs

A spin bike is excellent for hips and leg muscles, strengthening your quads, hamstrings, glutes, and hip flexors in particular.

People usually use ellipticals for non-impact exercises, putting less force on the joints and spine.

“In general, the elliptical machines are easier on the knees and other weight-bearing joints.”


- Eran Kabakov, Physical Therapist

Pedaling in reverse is also great for improving your legs physique. Plus, the handles on the ellipticals enable you to work on both your lower and upper body, providing you with a solid full-body workout.

Luckily, most cardio machines already have pre-built workout programs for engaging different muscles.

How Much Equipment Adjustability and Comfort Matter to You

The degree of adjustability, customization, and comfort your in-home exercise equipment allows will probably directly influence your workout results.

For example, a recumbent bike might be unbeatable for the elderly or recovering patients because it’s gentle, comfortable, and highly adjustable, letting you personalize your workouts. However, it’s far from ideal for any high-intensity workout session.


Which Cardio Machine Is Best for Abs?

A treadmill (used for running, not walking), an elliptical, a stationary bike, or a stair stepper may be cardio machines best for abs because they help you burn fat and calories most effectively [5] if you use them right.

Which Cardio Machine Is Best for Bad Knees?

A recumbent exercise bike is the best cardio machine for bad knees because it provides fantastic support to your body, allowing the positions that don’t cause too much stress on your knee joints.

Besides, indoor rowing machines and elliptical training machines could also be suitable for people with knee issues who want to lose weight or keep fit.

Which Is Better for Toning Legs Treadmill or Elliptical?

The treadmill is better than the elliptical for toning your legs.

But, according to the Mayo Clinic, unlike on treadmills, you can pedal backward on most elliptical machines, engaging your hamstring and calf muscles a bit more than when pedaling forward. [6]

What Cardio Machine Should I Use?

What cardio machine you should use depends on the factors mentioned above.

Now that you’re informed, put our list of exercise machines to the test for a couple of weeks before making your final decision.

I’d suggest going for the LifeSpan CYCLE BOXER, an innovative, all-encompassing, and entertaining fitness machine, mostly because of its versatility, functionality, and effectiveness.
