Rory checks in for full service

Rory McIlroy’s physical transformation — not to mention an even more important mental change — has been remarkable over the past four years and he was back at it yesterday when he made one of his regular trips to GlaxoSmithKlein’s Human Performance Laboratory in London.

“Back to work today @GSK_HPL #betterneverstops,” the new Open champion informed his 1.97 million Twitter followers, posting several pictures of another exhaustive and exhausting physical check-up. Back in April, he was pictured looking exhausted as he had his sweat composition analysed “after an hour on the watt bike in a heat chamber”. It was a similar tale back in February at a previous check-up.
