Proform Performance 400 C Treadmill Review
TREADMILL DOCTOR NOTE :
A cheap alternative for a Proform but not a very good treadmill.
The Proform Performance 400 C can, at best, be viewed as a cross trainer and you are better off using it as an entry level treadmill coupled with an elliptical to deliver more efficient calorie burn. For serious runners we say stay away from the Proform 400 and the 400 C. If you need a cheap unit at a bargain price, this one is it but only will last if you are a walker and baby it.
