Legs are generallly not a priority in a guy's workout. Chest, abs, arms, shoulders are usually ahead of legs and glutes... AS for Jimmy, I think he's kinda let himself go lately, so it's good if he's working out again. He was ripped back in movies like Gossip and Disturbing Behavior. Not so much in The Heights... It's hard to work out working in this industry. Especially, cause he has a family... Where does one find the time?
Back to Cyclops. I was a bit disappointed that none of the alternate endings hinted at Scott's survival. But as long as they don't do another X-Men film without him, I'm accepting it. His death actually doesn't happen until 40 minuites into a movie that's only an hour and a half.
