The gym and fitness classes at the Sovereign Centre reopened on Saturday (July 25) with strict hygiene and safety measures in place.
The centre was closed in mid-March under government guidance due to the Covid-19 pandemic.
Work is underway to prepare to reopen the gala pool in September.
Under social distancing rules, it is not yet safe to reopen the fun pool.
After 15 years of managing the Sovereign Centre, Serco Leisure passed management of the facility back to the council in June.
