This board is terrible! After weeks of debating , decided to give in and buy.
I am healthy, active abd in my early 30s. I stretched before use and only tried for ten mins because my legs started hurting. The next morning woke up with lower back pain. In a weeks time the pain increased and radiating down my leg.
Visited my doctor who says it is a compressed sciatic nerve. Gave me a shot of Torodol and is ordering PT. I am on my 9th day of back pain.
I recommend staying away from this product. It may cost you pain and additional money from doctors visits.
