FAQ
The Boost microgravity treadmill allows you to run or walk at anywhere from 100% to as low as 20% of your bodyweight, in 1% increments.
This reduction in effective body weight is achieved by creating a higher pressure around your lower body. Because this pressure is greater than the pressure outside the enclosure, it creates a lifting force which counteracts gravity. The lifting force is dispersed across your entire lower body, which makes it incredibly comfortable. This gives you a sense of walking or running in a totally normal way, while at the same time feeling incredibly fast, strong, and pain-free.
- Runners who want to decrease stress on the body while running additional mileage.
- Active individuals looking to add a recovery or cross training day into their routine.
- Those who have sustained or are returning from an injury.
