Frequently asked questions
What does ‘serious training’ mean for a treadmill?
Serious training typically involves running multiple times per week, incorporating intervals, hills, and longer distances. The treadmill should have a strong motor, durable construction, and sufficient incline range.
How much incline do I need for hill training?
For effective hill training, look for a treadmill that offers at least a 10 to 15 percent incline. Some models also offer a decline feature, which is useful for simulating downhills.
Is a subscription required for these treadmills?
Many high-end treadmills, like NordicTrack and ProForm, offer iFit, which requires a subscription for full interactive features. However, you can still use the treadmill manually without a subscription.
What is the maximum weight capacity I should look for?
For serious training, look for a treadmill with a weight capacity of at least 300 pounds. This ensures stability and durability, especially for taller or heavier runners.
How fast do these treadmills go?
Most treadmills for serious training reach speeds up to 12 mph, which is a 5-minute mile pace. Some go up to 15 mph, but 12 mph is sufficient for most runners.
Can I use these treadmills for walking?
Yes, they can be used for walking, but they are built for running. If you primarily walk, you might not need the higher motor power, but it doesn’t hurt to have it.
Do I need to lubricate the belt?
Yes, regular maintenance includes lubricating the belt according to the manufacturer’s instructions. This ensures smooth operation and extends the life of the treadmill.
How much space do I need?
Most treadmills require a footprint of about 6 feet by 3 feet, but you also need clearance on all sides. Consider foldable models if space is limited.
Final word
For serious training, the NordicTrack Commercial 1750 offers the best combination of incline range, motor power, and interactive features, but you should be comfortable with the iFit subscription. If you prefer a subscription-free option, the Sole F85 is a durable alternative with a strong motor and excellent cushioning.
