Not suitable for people with thin rotor arms

Yes, as a runner has one does not necessarily reflect the thick upper arms, but that part can I bind almost to the thigh.
Pity is that the velcro is not quite up to the end and thus about 2 cm are given away that you can not make close. So who has a few muscles, which is the part fit. For Lean and people with real thin upper arms, the tape is clearly too far and the adjustment possibilities are very deficient.
