The golden model has the optimum strength for someone who is a little trained. If an exercise threatens to simply be, the imagination knows no boundaries: There are endless possibilities of how to use this band expedient to torment all possible muscle groups. It can withstand extreme loads, such as very narrow handles any problems. To avoid having to expend more power, you can take the tape also double or single use more addition. In my view, however, not for people who are not trained enough and therefore not applying the control and body tension to plan and carry out clean exercises. For me personally optimal, very good, classic "equipment". Always happy!
