René Moos's gym chain Basic-Fit reported revenues of €76.9m (US$83.6m, £64.8m) in the first three months of the year as the group opened more clubs and grew membership numbers.

The low-cost European fitness operator's latest trading update shows that year-on-year revenues were up 27 per cent from €60.5m (US$65.8m, £51m) in 2016.

Chief executive Moos said the group “continued to outperform the market”.

Memberships increased to 1.33m in the first three months of 2017, a rise of 24 per cent from 1.08m in 2016.

Basic-Fit is on track to open 100 clubs this year after increasing its network by 21 to 440 in the January-March period. In total, 16 new clubs opened in France, three in Belgium and two in Spain. It also expanded the floor size of two existing clubs to enable further growth.

Moos added: “We remain confident that we will achieve the guidance of 100 club openings in 2017.”
