For example Siver can throw 45lb weights. Wear gym clothes. Just anything gym related. Annie and skip around with a weight belt besides a teddybear and throw out Tibber a big muscle bound powerlifter / bodybuilder.
for the whole powerlifter/bodybuilder thing you're going for,
Jogger 
(not in shape to do much else yet)
Bench Press 
(instead of a mercury hammer he has a 45 lb lift bar where the weights slid off one side while lifting because he's a noob)
Never skip arm day 
(simple enough, just wearing gym clothes and using a curl bar instead of his normal staff, but with a special emote where he curls the bar, and the weight gets bigger for the number of stacks he has)
There are probably a lot of other good candidates, but these stuck out to me.
