London-It is raining hard but Bradley, a fitness instructor, and four of his gym rats are sweating profusely while alternating between squats and abdominal exercises in a London park.

Some have yoga mats and others stretch out on the wet grass, muddying their shirts with stains. But there are few other options. While England’s beloved pubs are finally reopening along with the rest of the hospitality sector on Saturday, gyms are staying shut for at least a few more weeks.
