Andy Murray has appeared to step up his recovery from a hip operation after sharing a video of him hitting a tennis ball.

The three-time grand slam winner had a hip resurfacing operation in January as he attempts to overcome a problem that first surfaced in the summer of 2017.

And on Monday night, the 31-year-old shared a short clip on his Instagram Story of him hitting forehands and backhands against a wall, with the caption 'It's a start'.

Murray had a first operation in January 2018 and returned to action at Queen's Club last summer but played only six tournaments last season and was in pain throughout.

His last appearance came at the Australian Open, losing to Roberto Bautista Agut in a gruelling five-set match in the first round, but has said since his surgery that he would love to be able to play at Wimbledon in July.
