Investing in a high-quality treadmill is one of the best decisions you can make for your home gym. Treadmills allow you to get in cardio workouts anytime, regardless of weather or daylight. While standard flat treadmills suffice for walking and light jogging, serious runners benefit from curved treadmills that better simulate road running.
Curved treadmills feature a subtly convex deck that matches the natural gait of outdoor running. This reduces impact on joints while engaging core musculature more. The design also encourages a longer stride to build speed. If you want to level up your treadmill training, a curved model is the way to go.
This article will review the top 4 curved treadmills on the market and provide tips for choosing the best model for your fitness needs and budget. Let’s get started!

How to Choose the Right Curved Treadmill
With the top models covered, let’s explore how to select the ideal curved treadmill for your fitness objectives, space, and budget:
- Consider your main uses – walking, jogging, running, sprints, hills? Curved treadmills excel for serious runners.
- Deck size – Standard is 20” x 60”. Taller runners need at least 4-5” extra width than natural stride.
- Cushioning – Look for models with quality cushioning systems to absorb impact. These reduce joint pain.
- Motor power – At least 3 CHP is recommended for a robust motor able to handle running and declines.
- Incline range – Steep inclines like 12%+ simulate hill climbs indoors. Go manual or motorized.

- Warranty – Lifetime frame and motor coverage is ideal. Multi-year parts/labor provides peace of mind.
- Space – Measure your workout room. Curved decks need more length than flat treadmills.
- Budget – Quality curved treadmills range from $1500 for basic models to $4000+ for the top tier.
