We use the local hidden gauge approach in order to study the $B\bar{B}^*$ and$B^*\bar{B}^*$ interactions for isospin I=1. We show that both interactions viaone light meson exchange are not allowed by OZI rule and, for that reason, wecalculate the contributions due to the exchange of two pions, interacting andnoninteracting among themselves, and also due to the heavy vector mesons. Then,to compare all these contributions, we use the potential related to the heavyvector exchange as an effective potential corrected by a factor which takesinto account the contribution of the others light mesons exchange. In order tolook for poles, this effective potential is used as the kernel of theBethe-Salpeter equation. As a result, for the $B\bar{B}^*$ interaction we finda loosely bound state with mass in the range $10587-10601$ MeV, very close tothe experimental value of the $Z_b(10610)$ reported by Belle Collaboration. Forthe $B^*\bar{B}^*$ case, we find a cusp at $10650$ MeV for all spin$J=0,\,1,\,2$ cases.
