The Active Run 400 Smart is a smart treadmill designed to let you enjoy the sensations of running outdoors without having to leave your home. Thanks to Smart technology, you can enjoy personalized and challenging workouts in the virtual world while the treadmill automatically adapts to the different inclines and speeds of the virtual routes. The Active Run 400 Smart has a great set of features that make it a true all-rounder among treadmills: its motor is capable of reaching 16 km/h, it has 15 automatic incline levels, a large running surface of 122 x 42 cm, heart rate monitors and buttons to control the incline and speed from your arm, etc. However, what makes it stand out from other treadmills is its Shocks® & React cushioning system that adapts to each type of stride and the SA Mode system, an air shock absorber capable of modifying the hardness of the tread up to 4 levels. This way, the user can simulate different types of terrain and better prepare for a future race. This also helps to protect their joints. As for the console, the Active Run 400 Smart features a very complete system, with a Start/Stop button, an SA Mode button so you can adjust the treadmill's treadmill hardness, three buttons with different preset speed levels, buttons to increase and decrease speed and incline, a button to mute the music, and two buttons to skip songs that, if held down, can adjust the volume. Finally, this treadmill features two drawers and a tablet or mobile phone holder for comfortable use during workouts. At the bottom of the console, we find the MP3 connector, the USB port, and the speaker outputs so you can listen loudly to the music that motivates you
