Not one to normally show off his physique, Affleck is most commonly seen out wearing baggy sweatshirts, jeans and loose T-shirts that cover his body.

Affleck - who has played superheros before in Daredevil and as George Reeves, the actor who played Superman in the 1950s TV show Adventures of Superman, in 2006's Hollywoodland - has reportedly been working out twice a day to bulk up.
A longtime client of trainer to the stars, Gunnar Peterson, Ben also follows the guidance of Boston Celtics strength and conditioning coach Walter Norton Jr when he wants to build muscle.
Its far from the first time that the Runner, Runner star has had to transform his body for a role, most recently in 2010 for crime-thriller The Town.

'I was playing this guy who was supposed to be very tough, a professional hockey player, then he got into drugs and he quit and re-dedicated himself furiously to this workout regimen,' he told Access Hollywood.
'And I saw that and I didn't think about it too much - and then six months out I panicked and realized I have to transform my body, or I will be a complete fraud, and I will be derided openly, nakedly. I just didn't want to ask for all this reality from everyone else and not have it myself.
'It was horrible, horrible - but all worth it.'

Gym rat: Ben has no doubt been doing plenty of squats and lunges with Gunnar Peterson to tone up

Affleck was a controversial choice for the part of DC Comics-based film when it was announced in August that he would follow in the footsteps of Christian Bale, Val Kilmer, George Clooney and Michael Keaton to play the Caped Crusader in the 2015 movie, but driector Zack Snyder defended the decision, reported Us Weekly.
'Ben provides an interesting counterbalance to Henry's Superman, He has the acting chops to create a layered portrayal of a man who is older and wiser than Clark Kent and bears the scars of a seasoned crime fighter, but retain the charm that the world sees in billionaire Bruce Wayne.
'I can't wait to work with him.'
