What Defines Treadmills
Treadmills are motorized cardio machines that provide a moving belt surface for walking, jogging, or running indoors. Unlike other equipment in the Fitness category, treadmills offer the most natural running experience while allowing precise control over speed and incline for consistent cardiovascular workouts.
How to Choose Treadmills
Consider these important factors when selecting a treadmill:
Motor Power
Determines durability and performance - 2.5+ HP continuous duty motors handle regular running, while lower power suits walking only
Running Surface Size
Larger belts (20" wide minimum) provide safer, more comfortable running with natural stride length
Available Space
Measure your area carefully - folding models help, but check folded dimensions and weight for moving/storage
Intended Use
Walking requires less power and features than serious running - match the machine to your fitness goals
Weight Capacity
Choose models rated 50+ pounds above your weight for stability and longevity
Common Tradeoffs
Price vs. Durability
Budget models under $500 often have weaker motors and shorter lifespans, while premium units offer commercial-grade components but cost significantly more
Features vs. Simplicity
Basic models focus on essential functions and reliability, while feature-rich treadmills may have more potential maintenance issues
Size vs. Portability
Larger running surfaces provide better workouts but require dedicated space, while compact folding models may feel cramped for taller users

Frequently Asked Questions
How much motor power do I really need?
For walking and light jogging, 2.0-2.5 HP continuous duty is sufficient. Serious runners should look for 3.0+ HP motors to handle sustained high-speed use without overheating.
Are folding treadmills as sturdy as non-folding models?
Quality folding mechanisms can be quite robust, but non-folding treadmills typically offer better stability during intense workouts. The tradeoff depends on your space constraints versus performance needs.
What's the difference between peak and continuous duty horsepower?
Continuous duty HP represents sustained power output during normal use, while peak HP is a brief maximum that's not sustainable. Always focus on continuous duty ratings for accurate comparisons.
How much space do I need around a treadmill?
Plan for at least 6 feet behind the treadmill and 2 feet on each side for safety. Also ensure adequate ceiling height - 8 feet minimum for most users.
