Every body isn't as strong otherwise they wouldn't be able to take him down at the party and my guess is there's a Wakandan Vibranium infusion somewhere along the line of forms. But as said that looked like a drone
The niggle I gather for some isn't Cap struggling it's that in these short trailers and the BTS clips we haven't seen anything but yet. As of now there's nothing to ooh and ahh over with Cap. There's no inventiveness to the fights or his physicality yet. We've seen Thor light up and float, Tony in a Hulkbuster going at it with Hulk, Natasha dropping out of a quinjet on a motorcycle and taking down two guys with that leg jump with teases of her past, SW doing her magic and QS going fast and we've seen Steve... punching and kicking open a door. Also to be fair, looking very nice walking away and standing in profile.
So yeah nothing to tease us yet that Steve will be at TWS level. I'm willing to wait though.
my problem with it is not how badass Cap will be in the fighting, which as much as they have the same stunt coordinator from Cap2, the fighting style won`t be as spot on, since in Cap2 they were more "grounded", he could show his martial arts style, while here Cap will be jumping all over the place.. but I don`t even care much about his fighting style, but I see a "lack" of Cap in the trailer, or something that teases he will lead the Avengers, I`m not talking about giving orders in the battle field, but the greatness of having Cap actually giving an inspiring speech like he had in TWS, that is Cap! he is not doing impressive fighting stuff compared to the other Avengers, other than his gymnastic abilities, but he inspires others.
And I know you are all like "ug fanboy complaining" as if I`m not entitled to my own opinion (I`m sorry not everyone adores Whedon and his work)... and call me "fangirl" please
I just see a lot of IM around in the trailer like in TA and well ... I don`t trust Whedon`s delivery, in particular with that character, though he was great with IM and Hulk... with the rest they are just fillers for him.
I hope that by setting my expectations really low, I will be surprised then in a good way, once the movie is out

ps, does it bother you all that I`m on the "verge of a panic attack"? LOL
seriously people don`t take it personally because there is someone who doesn`t like something, can you all be nicer and we can have a conversation then?...
