Treadmills make it easy to train at home, hit the weekly 150 minutes of moderate cardio, and stay consistent even when the weather doesn’t cooperate [1], [2].
If you’re feeling overwhelmed by models and specs, you’re not alone. Use this simple guide to choose the right machine for your space, goals, and budget.

Which Is Better: Folding or Non-folding?
Folding treadmills save space and often have transport wheels. They’re great for apartments and multipurpose rooms.
Stability depends on the folding mechanism and overall build. Mid- to higher-tier folding models can feel as solid as non-folders.
Non-folding treadmills are the standard in commercial gyms for a reason: fewer moving parts and a heavier, welded frame usually mean rock-solid stability and long-term durability.
Quick tip: If you won’t move the unit often and you have the space, a non-folding frame is the easy pick for the most stable feel.
The Frame
A heavier frame usually runs quieter and shakes less at speed. That means a more comfortable workout.
Check maximum user weight and add a buffer. A higher rating often signals stronger materials and parts.
If multiple people will use the treadmill daily, lean toward commercial or “light-commercial” frames for longevity.
The Motor
Look for continuous-duty horsepower (CHP), not peak HP. CHP reflects power the motor can deliver over time.
Simple rule of thumb: walking ~2.0+ CHP, jogging ~2.5–3.0+ CHP, running ~3.0–4.0+ CHP. Heavier users or sprint work benefit from more.
Higher-quality motors hold belt speed better when your foot strikes, keeping intervals and long runs consistent.
The Deck & Belt
Size matters. Many runners feel comfortable around ~51 cm x 152 cm belts, while walkers can use shorter decks. Taller users and sprinters may prefer longer, wider belts for toe-off room [8].
Cushioning helps reduce impact and improve comfort. You can add a slight incline (1–2%) to better mimic outdoor effort and alter joint loading patterns [6].
Rollers & belt quality affect smoothness and maintenance. Larger rollers and thicker, multi-ply belts generally wear longer.
Control Panel & Safety
Choose a console with quick buttons for speed and incline so you can change pace safely mid-workout.
Make sure there’s a working emergency stop/safety key that clips to your clothing. It should immediately stop belt motion if pulled [3], [4].
If you have kids or pets at home, treat a treadmill like any large appliance—unplug when not in use and keep the area blocked. In 2019, an estimated 22,500 treadmill injuries were treated in U.S. emergency departments, including about 2,000 in children under age 8 [5].
Entertainment & Smart Features
Bluetooth audio, app connectivity, and quick-start programs can make longer sessions fly by.
If training with virtual platforms is your thing, check for compatibility and Wi-Fi/Bluetooth support.
Wrap Up
Match the treadmill to your goals, space, and users. Focus on frame stability, CHP rating, deck size, and safety.
From there, add the smart features you’ll actually use. Consistency beats bells and whistles every time [1], [2].

Treadmill Buyer’s FAQ
What motor size (CHP) do I need?
Use CHP as your guide. For walking, look around 2.0+ CHP. For jogging, 2.5–3.0+ CHP is a safer bet. For regular running or intervals, aim for 3.0–4.0+ CHP, especially if you’re heavier or plan to sprint. A stronger motor keeps set speed under foot strike and reduces strain on parts. Prioritize reputable brands and longer warranties for daily use.
What belt size is right for my height and stride?
Comfort and safety improve when the belt fits your stride. Many runners like ~51 cm x 152 cm as a baseline, while walkers can go shorter. Taller runners or anyone doing fast intervals may prefer longer/larger decks to avoid “short-striding.” If you’re near the limits, size up for extra toe-off room [8].
How much space should I leave around a treadmill?
Plan for clear space on both sides and behind the deck for emergency dismounts. Industry guidance based on ASTM suggests roughly 0.5 m on each side and about 2 m behind the treadmill. This helps reduce fall risk and makes maintenance safer [9].
Are treadmills good for meeting weekly cardio goals?
Yes. Treadmills make it easy to hit the recommended 150 minutes of moderate or 75 minutes of vigorous activity each week. You can split this into short bouts across days, and add two strength sessions for extra benefits. Walking at an incline or doing intervals are efficient ways to boost intensity [1], [2].
Is treadmill running different from outdoor running?
They’re more similar than most people think. Reviews of the research show treadmill and overground running share comparable biomechanics and physiology, especially when you add a small incline to better match outdoor effort. Expect minor differences, but training carries over well between the two [6].
Which safety features matter most?
Prioritize an accessible stop control and a functional safety key that clips to your clothing, plus sturdy side rails. These features are part of widely referenced treadmill design standards and are emphasized in independent safety testing. If you have kids or pets, unplug the treadmill and restrict access when it’s not in use [3], [4], [5].
