There's no one-size-fits-all "best" cardio machine - only the right one for your goal. The treadmill burns the most calories per hour (600–1,000 kcal) and is unbeatable for endurance and fat loss. The rowing machine is the most joint-friendly full-body option and engages around 70–85% of your muscles with minimal stress on your knees and hips. The air bike is the king of HIIT - no other machine drives your heart rate up faster or burns more calories in less time.
The choice comes down to three factors: your training goal, your space and your motivation. This article helps you make the right call.

Rowing machine: The full-body all-rounder
A rowing machine simulates the motion of rowing on the water. You drive off with your legs and pull the handle toward you - a synchronized movement of your legs, core, back and arms.
Pros of the rowing machine
Up to 85% of your muscles are engaged. No other cardio machine recruits this much muscle mass at once. Every stroke works your legs, glutes, core, back, shoulders and arms - making the rower the most time-efficient full-body cardio option.
Almost no stress on your joints. Unlike a treadmill, there's no impact. The rower is ideal for people with knee, hip or back problems who still want to burn calories effectively.
Calorie burn on par with the treadmill. If you can't or don't want to run, you can burn 500–800 kcal per hour on a rower - about as much as running, but with zero impact.
Compact and space-saving. A rower is long and narrow (approx. 241 × 62 cm), but slimmer than a treadmill. Many models also fold up.
Cons of the rowing machine
- You have to learn the technique - the rowing stroke is demanding in terms of coordination. Poor form (especially when you're fatigued) can lead to back pain.
- Not intuitive for everyone - if you just want to "start running," you're better off on a treadmill.
- Less suited to heavy leg work - a rower isn't a leg press. For maximum leg muscle growth, the treadmill (sprints, incline) has the edge.
ATLETICA MagnaRow: The dual-resistance rower
The ATLETICA MagnaRow combines 10 levels of air resistance with 6 additional magnetic levels - a unique dual-resistance system. Air resistance is great for cardio and muscular endurance, while the extra magnetic levels are made for heavy strength work (similar to a seated row machine).
- Rated up to 160 kg, built for commercial use (EN 957)
- Folds into two parts (137 cm + 122 cm) - stores away in minimal space
- Self-powered display - no outlet needed
- Large 5.5-inch LCD display showing calories, watts, distance, time, split (time/500 m) and heart rate
- Smartphone holder and Bluetooth/ANT+ compatibility for app tracking
- TÜV-certified to EN957-1 and EN957-6
- 5-year warranty on the base frame
The MagnaRow is ideal for serious home gym owners looking for joint-friendly full-body training - who also want to build muscular endurance with the magnetic levels.
Treadmill: The calorie king
A treadmill is the classic cardio machine: You run or walk on a moving belt with adjustable speed and incline.
Pros of the treadmill
The highest calorie burn of any cardio machine. A recent study compared ten cardio machines and concluded that the treadmill and stair climber outperformed the elliptical, rower and bike in calorie burn. To burn 300 calories at an exertion level of 13 ("somewhat hard"), participants only had to run for 23 minutes, but row for 32 minutes.
The easiest to use. Everyone can run. There's no learning curve and no technique to master. That lowers the barrier to entry and makes it more likely you'll actually use the machine regularly.
Versatile. From a leisurely walk to zone 2 training to intense interval sprints - no other machine covers so many intensity levels.
Calorie burn depends on body weight. The heavier you are, the more calories you burn on a treadmill - a built-in advantage for people with a higher body weight.
Cons of the treadmill
- High joint stress - running is a high-impact sport. With every step, your knees, hips and ankles absorb several times your body weight.
- Loud - the motor and footsteps create noise that can be a problem in apartments.
- Takes up a lot of space - a treadmill often needs 6 × 3.5 ft (approx. 183 × 107 cm) or more.
- High maintenance - belts need to be lubricated and motors serviced.
ATLETICA SprintMaster PRO: The high-end treadmill
The ATLETICA SprintMaster PRO is a high-end treadmill with an Android display and a powerful 6 HP AC motor that reaches top speeds of up to 25 km/h - ideal for intense interval training.
- Incline up to 15% for uphill training and a higher calorie burn
- Running surface: 158 × 60 cm - roomy for every stride length
- Maximum user weight: 160 kg
- Android console with built-in sound system and headphone jack
- Certified to EN ISO 20957-1:2013
- Dimensions: 214.5 × 93 × 168 cm (L × W × H)
- Net weight: 198 kg - built heavy for stability
The SprintMaster PRO is the right choice if you're after maximum calorie burn, endurance training and the option for intense interval training - and you have the space for it.
Air bike: The HIIT king
An air bike (also called a fan bike) is a stationary bike with a large fan wheel that provides the resistance. The harder you pedal and pull, the greater the resistance. There's no coasting, no break - just you and the air resistance.
Pros of the air bike
The fastest heart rate spike. No other cardio machine drives your heart rate up this fast. After just 10–15 seconds of all-out effort, even experienced athletes are out of breath.
Maximum time efficiency. A 10-minute HIIT workout on an air bike can be more effective than 30 minutes of moderate cardio. Perfect if you're short on time.
Arms and legs work at the same time. Unlike on a treadmill or rower, you work your arms and legs simultaneously - which increases muscle activation and calorie burn per minute.
Very compact. An air bike only needs about 122 × 61 cm - much less space than a treadmill or rower.
Low maintenance. The mechanics are simple: chain, bearings, fan wheel. No motor, no electronics, no complicated upkeep.
Cons of the air bike
- Very loud - the fan wheel sounds like a jet engine. That's a problem in apartments with thin walls.
- Not suited to easy cardio - you can't train "relaxed" on an air bike. The intensity scales directly with your effort.
- High barrier to entry - for beginners, the intensity can be overwhelming. Slow, steady-state training is hardly possible.
- Limited calorie burn over long sessions - most people can't go all out on an air bike for more than a few minutes. It's not suited to hour-long cardio sessions.
Air bike: Who it's for
The air bike is the right choice if you:
- love HIIT and prefer short, intense sessions
- do (or want to do) cross-training or functional training
- are short on time and want maximum efficiency
- have limited space (e.g. a small apartment, garage)
- want to improve your conditioning fast
The scientific perspective: What the research shows
Calorie burn
A study by Jensen et al. (2019) compared ten cardio machines at different intensity levels. The result: The treadmill and stair climber led to a significantly higher calorie burn than the elliptical, rower and bike. To burn 300 calories, it took only 23 minutes on the treadmill but 32 minutes on the rower.
The air bike wasn't directly compared in this study, but other research shows that at all-out intensity, the calorie burn on an air bike can match or exceed that of a treadmill. The problem: Hardly anyone can keep up that pace for more than a few minutes.
Joint stress
The rower and the air bike are non-impact machines - they put much less stress on your knees, hips and ankles than the treadmill. For people with joint problems or coming back from an injury, they're the better choice.
Muscle activation
The rower engages up to 85% of your total muscle mass - the highest muscle recruitment of any cardio machine. The air bike follows close behind, because your arms and legs work at the same time.
HIIT vs. LISS
A study in the Journal of Physiology (2019) showed that HIIT can achieve the same effect in 20–30 minutes as 60 minutes of traditional cardio. For time efficiency, the air bike (or interval training on a treadmill/rower) is the best choice. For fat loss and endurance, LISS (low-intensity steady state) on a treadmill or rower is ideal.

Frequently asked questions
Which cardio machine burns the most calories?
The treadmill burns the most calories per hour (600–1,000 kcal). At all-out intensity, the air bike can reach similar numbers, but most people can only keep that pace up for a few minutes. The rower comes in at 500–800 kcal per hour - about as much as the treadmill, but with less stress on your joints.
Which cardio machine is easiest on the joints?
The rower and the air bike are the most joint-friendly options. Neither involves any impact. People with knee, hip or back problems should avoid the treadmill or only use it for walking/incline walking.
Is a rowing machine better than a treadmill?
That depends on your goal. For maximum calorie burn, the treadmill comes out ahead. For full-body training that's easy on the joints, the rower is better. Both are effective - the best choice is the machine you'll actually use regularly.
Which is better: air bike or treadmill?
The air bike is better for HIIT and time efficiency - in 10 minutes, you'll get what takes 20–30 minutes on a treadmill. The treadmill is better for endurance, steady-state cardio and maximum calorie burn over longer periods.
How much space do I need for a rowing machine?
A rowing machine needs about 241 × 62 cm (length × width). The ATLETICA MagnaRow folds and splits into two parts (137 cm + 122 cm) - ideal for small rooms.
Can I build strength on a rowing machine too?
Yes, the ATLETICA MagnaRow has a unique dual-resistance system with 10 air resistance levels plus 6 additional magnetic levels. The magnetic levels (11–16) are made for heavy strength work and muscular endurance - similar to a seated row machine.
Which cardio machine is best for beginners?
The treadmill is the easiest - everyone can run. The rower requires technique, and the air bike is very intense. For absolute beginners, walking on a treadmill or rowing at low intensity is ideal.
