The Professional Package is another package made exclusively for the serious athletes and weight lifters. This package is just like the Master's Package except this package also includes #6 Extra Large bands. These bands make performing bench exercises and squatting exercises very difficult. These #6 Extra Large bands offer a considerable amount of pressure to your joints, ligaments, and tendons, making them super strong super fast. This package is not one to be taken lightly. This package contains pairs of #1 Mini, #2 Super Mini, #3 Small, #4 Medium, #5 Large, and #6 Extra Large Bands.
