Not sure which cardio machine is right for you? Take our Cardio Machine Quiz — it analyzes your goals, joint health, space, and budget to give you a definitive answer.
The Quick Answer
For most home gym owners, a rowing machine wins. It burns more calories per minute, works 86 percent of your muscles in a single movement, is easier on your joints than running, stores more compactly than a treadmill, and costs less at comparable quality levels.
The treadmill wins if you are a dedicated runner training for road races, or if walking is your primary form of exercise and you need the stability of a treadmill for safety or health reasons.
Everything else — weight loss, general fitness, HIIT training, full-body conditioning — the rower handles better. Here is the detailed breakdown.
Calorie Burn Comparison
Calorie burn is one of the most common reasons people buy cardio equipment. Here is how the two machines compare for a 180-pound person working at moderate intensity for 30 minutes:
Space Requirements
Space is often the deciding factor for home gym owners. Here is how they compare:
- Rowing machine in use: Approximately 8 to 9 feet long by 2 feet wide — similar to a treadmill in use
- Rowing machine stored: Most quality rowers store vertically against a wall, taking up just 2 to 3 square feet of floor space
- Treadmill in use: 6 to 7 feet long by 3 feet wide — roughly the same as a rower
- Treadmill stored: Folding treadmills collapse to a smaller footprint but cannot store vertically — they always occupy floor space
The rowing machine's ability to store vertically is a significant advantage for home gyms where every square foot matters. A Concept2 rower standing upright takes up about the same space as a kitchen chair.
Cost Comparison
At comparable quality levels, rowing machines are generally less expensive than treadmills:
- Budget rowing machine (entry level): $200 to $400 — functional but noisy, magnetic resistance
- Mid-range rowing machine: $500 to $800 — solid build quality, quieter, suitable for daily use
- Premium rowing machine (Concept2): $900 to $1,100 — commercial-grade, used in Olympic training facilities, lasts indefinitely
- Budget treadmill: $300 to $600 — underpowered motors that burn out with regular use
- Mid-range treadmill: $800 to $1,500 — suitable for moderate use, decent motor and cushioning
- Premium treadmill: $1,500 to $3,000+ — commercial-grade running experience with full cushioning and powerful motor
The Concept2 RowErg is universally considered the best rowing machine in the world — used in commercial gyms, CrossFit boxes, and Olympic training facilities. At $900 to $1,100, it is comparable in cost to a mid-range treadmill but significantly more durable and effective. Concept2 rowers regularly last 15 to 20 years with minimal maintenance.
Joint Health and Injury Risk
This category is where the rowing machine pulls decisively ahead for many people. Running on a treadmill is a high-impact activity — every stride sends a force of roughly 2.5 times your body weight through your knees, hips, and lower back. For people with existing joint issues, this impact accumulates quickly and can lead to overuse injuries.
Rowing is a low-impact exercise. The movement is smooth and continuous with no jarring impact. People who cannot run due to knee or hip problems can often row comfortably and intensely. If you have any history of joint issues, this distinction alone should drive your decision.
The one caveat: rowing requires proper technique to avoid lower back strain. Learn the correct rowing stroke before training at high intensity. Most manufacturers include instructional videos, and proper form is not difficult to learn.
When a Treadmill Is the Right Choice
Despite the rowing machine's advantages, there are situations where a treadmill is genuinely the better option:
- You are training for a running event — marathons, half marathons, or 5Ks. Running specificity matters and nothing replaces actual running.
- Walking is your primary form of exercise. Incline walking on a treadmill is an excellent low-impact fat-burning workout that a rowing machine cannot replicate.
- You genuinely enjoy running and will use the treadmill consistently. Consistency beats efficiency every time — the best machine is the one you actually use.
- You have young children at home who need supervised exercise — walking on a treadmill is safer and simpler to explain than teaching rowing technique.
The Verdict
If you are buying one cardio machine for your home gym and your primary goals are burning fat, improving cardiovascular fitness, or conditioning for general health — buy a rowing machine.
The Concept2 RowErg is the definitive recommendation. It is the only piece of cardio equipment that virtually every fitness expert, CrossFit coach, personal trainer, and Olympic athlete agrees on. It is the gold standard for a reason — and it will outlast every treadmill in the same price range by a decade or more.
If you are a runner, buy a treadmill. Everyone else should row.
