Murray has been stepping up his conditioning ahead of the hardcourt season in preparation for the US Open with a “brutal” new training regime in the hopes that can be the edge in long matches. “I mean, I got here pretty early,” he said ahead of the tournament. “We arrived on Tuesday night, so yeah, try and get used to the humidity.
“Obviously I had quite a lot of issues last year during American summer with cramping and stuff like that. I wanted to make sure I got here early to give myself enough time to adjust to that. It’s been good.
“So in preparation I was doing a lot of bike sessions. I put the bike in there and we can open the steam room a little bit to increase the humidity – obviously [turn on] the heaters to get the heat in the room up. Set it to like 35 degrees celsius and, like, 70 per cent humidity and then I would do my bike sessions in there.”
