Heat up your workout

TRX Annihilator

This signature class from new studio Ethos, situated in a luxurious space above Old Spitalfields Market, is not for the faint-hearted. A combination of cardio drills and TRX moves makes this class a real calorie burner, even without the  heated studio. Ethos also has a beautiful hot yoga studio, complete with fountain wall, and a ‘non air-conditioned’ performance-style indoor cycling class, believe us, this class feels heated.

Costs £20 per class (there are introductory and package deals available); ethos.co.
