This model is probably 8 years old. Works great and I'm not sure of the weight limits but I think 300 lbs. I bought this off HSN and the current model holds 300 lbs and this model is the same size as the one shown on their website and is very durable.
This is a great buy-its not brand new but it works great and the new ones are selling on hsn.com for $300.00
If you want to loose weight and tone up easily this is the real deal and it's easy and easy on the knees.
