26-year-old American singer Charlie Puth has really transformed his body in the past year – and it shows. In one of his recent Instagram posts, Charlie shared a gym video, showing him doing pull ups – and his arms are… impressive.

Charlie Puth is no stranger to teasing his fans with shirtless selfies. But it’s not just the fans – Shawn Mendes also opened up about getting gym selfies from Charlie, and for good reason.

Looking like that takes a lot of hard work (and some good genes) – and Charlie’s video shows him doing 16 pull ups at the gym (OK, we only see the last few…)

Those arm muscles sure are impressive, as is the rest of his upper body.

And yes, he is first and foremost a singer – but his looks are like music to our… err… eyes?
