    Very Little Resistance
  

*by S***I on Reviewed in the United States on December 17, 2011*

I am a somewhat advanced trainer and these just don't offer the amount of resistance that I need.  I find it hard to believe anyone could build calves using these.  If the bands were stronger this might be a good product.  Maybe I'll try to find something else to use with the straps.
