Fierce Grace Primrose Hill
Time Out says
With a manifesto that includes ‘reaching to the deepest places in yourself’ (mightn't that pull a muscle?), Fierce Grace sounds extreme. The reality is a lot like Bikram, though not as sweltering, with postures that flow more smoothly. The classes range from 50 minutes – ‘The Fix’ – to 1 hour 46 minutes – ‘The Beast’ and involve a series of yoga positions in a 38C hot room.
