Nick Kyrgios isn't into grass-court weight-lifting, which is one reason he declined buddy Andy Murray's doubles invitation for Wimbledon.
Former world No. 1 Murray will launch his return to the pro circuit on Thursday partnering Feliciano Lopez in doubles.

Kyrgios declined Murray's invitation to join forces in the Wimbledon doubles field, joking "I don't think I want to carry him for Wimbledon dubs. I think he can find someone else to do that for him."
The 39th-ranked Aussie, who hit with Murray on grass last month, said he's impressed with the Scot, who underwent hip resurfacing surgery in January.
"Andy was the first person I saw here, doing his drills," Kyrgios told the media in London. "I couldn't believe what I was seeing. Just to see him healthy and happy on court is all that matters."
A year ago, Kyrgios hammered 18 aces, nearly hit double digits in tweener attempts and played entertaining and exasperating tennis spoiling Murray's Queen's Club comeback, 2-6, 7-6 (4), 7-5, to reach the Fever-Tree Championships second round.
Asked why he relates to Murray, Kyrgios cited the Scot's humor and humility.
"He's a normal person," Kyrgios said of Murray. "When I hung out with him, he was funny. Didn't take himself too seriously. Every time I hung around him, I felt comfortable around him all the time. He kind of felt like he was, like, 20. He was a little bit immature at times. He was so friendly, humble, down-to-earth. Just a normal guy."
