I’ve visited four European gyms / workout facilities. Two accepted me, two didn’t. The two that didn’t did so because they don’t have “day passes” or guests. Why? Because they don’t want to be liable for any injury on their equipment. What a stupid policy. They should adopt the policy of the other gyms I’ve been to — and every gym in the States I’ve been to — which is to have guests / visitors sign away all their rights on a liability form, pay 10-15 euros, and let them in.
