On advice of my neurosurgeon, I am enrolled in a muscle strengthening program to tackle my chronic back pain. The weight is ideal, I use it in multiple excercises. I thought 5 Ib may be a little less but infact when used properly, it is of sufficient mass (for me). It is made of top quality material, looks and feels sold. Construction is such that it is easy to move around and store, doesn't roll away. A 5 star product.
