England cricketer Chris Tremlett may have retired from competition in 2015, but that doesn’t mean the former bowler has stopped training.

In fact, the 6′7″ giant looks like he hasn’t left the gym for a while.

And to be clear: It’s not like Tremlett wasn't muscular when he was playing for England’s national squad, or at both Hampshire and Surrey professionally. But he’s taken things to another level since hanging up his bat. Tremlett’s playing weight back then was 187lbs, but he’s bulked up to over 270lbs—and it looks like it’s pure muscle.

Here’s one look at how Tremlett sculpted his transformation—deadlifting 450lbs in the gym:

 

Progression... 205kgs. 5 reps. Never deadlifted till 6 months ago so happy with my progressions so far. 👍🏻👊🏻

Tremlett’s body transformation—like Bollywood stars Aamir Khan and Kunal Kapoor, and NBA star Julius Randle—is a pretty impressive one.

Here are 15 looks at Tremlett which prove he really pumped things up.
