How celebs REALLY keep their bodies in shape – from Cristiano Ronaldo’s £100k ice chambers to J-Lo’s trick for abs

WANT to get fit like a celebrity? Then you might need to shell out a few grand.

Cristiano Ronaldo recently posted pics from a Cheshire gym’s cryotherapy chamber with his 11-year-old son, Cristiano Jr.

Costing up to £100,000 for one of your own, the freezing cold rooms are said to boost metabolism, speed up recovery and help you lose weight faster.

It might sound straight out of a sci-fi movie, but the Manchester United striker isn’t the only celeb turning to trendy technology to stay in peak condition.

From infrared saunas to emerald lasers, stars are queueing up to throw money at the latest gizmos, gadgets and fads.

Here, we reveal the hottest new treatments - and some budget-friendly swaps you can try out at home.

Cryotherapy – soothes muscles
