I do a lot of computer work for my occupation, and it has been vital for me to take breaks and either stretch out or get exercise.  This purchase, along with an exercise ball and a yoga mat, have been absolutely essential for me to maintain my flexibility, strength, and overall health. These resistance bands are key for convenient strength exercises.  They seem to be built with high quality standards.  And the door anchor works great to add new dimensions to the exercises.  Highly recommend bringing this set into your home or office, or both.
