Interactive Calorie Center - When you input your weight and the number of calories you want to burn, the ProForm 510i counts them down!

Two Weight Loss, Two Distance Workouts - Two built-in distance workouts and two built-in weight loss workouts adjust the incline and speed of the treadmill for you, helping you achieve your 5K and 10K distance-training and weight loss goals.

Power Incline Control - Change the incline of the treadmill up to 10%. When you raise your intensity with a greater incline, you can burn more calories at lower speeds.

Cushioning - The impact-reducing cushioning gives you a more comfortable workout. It also reduces the impact on your joints by up to 15 percent compared to running on a hard surface.

Display: The backlit display is very easy to read. It features a wide viewing angle that allow full vision regardless of your height. You'll have the information you want because the display tracks your speed, distance, time, pulse and calories burned.

Speed Control - Instead of having to scroll through speed options, the 510i allows you to change your speed from 0-10 mph with one button as you are running.

Heart Rate Monitor - Make sure you are in your best training zone by holding on to the grip sensors.

Workout Fan - Stay comfortable and work out longer with the fan built into the console.
