Chris Evans gave fans a treat when he showed off his buff new physique on the set of the Captain America sequel.
The actor - who is reprising the role of Steve Rogers/Captain America in Captain America: The Winter Soldier - was snapped looking muscly as he shot scenes for the film in Washington DC, where fans gathered to get a glimpse of the stars.
Wearing a tight-fitting grey T-shirt, Chris was seen performing push-ups and jumping jacks and chatting to co-star Anthony Mackie as they worked on the eagerly anticipated movie.
They was joined by Scarlett Johansson, who was clad in her slinky Black Widow leather costume as she sat on set.
Video footage that has emerged online showed Scarlett and Chris shooting a scene in which the actor's character gets into a black car driven by the actress' Russian spy alter-ego.
Captain America 2 will also see Samuel L Jackson reprise his Marvel Comics role as SHIELD leader Nick Fury, while Robert Redford is to play Agent Alexander Pierce, a senior leader within the SHIELD organisation.
The film is scheduled for release in April 2014.
