Very well made vibration machine for the price. I have more than 35 years experience in sports medicine and fitness industry. Research showing positive results from oscillation platforms is compelling. Of course, one actually has to use it to get results. Don't be a fitness closet person. Keep this out where you can conveniently get on it multiple times per day for 3-5 minutes of squats, toe raises, etc., done with very slow movements. Hold squats at 90-degree knee position - you will feel your muscles responding. Improves balance, too.
