Apart from the manly aspect (even though its a woman on the website) press ups are a great exercise, good for your core and upper body which can sometimes be neglected by cyclists. The fact someones put a figure of doing 100 on it is simply to present a target (and it probably comes from schoolboy 'how many pressups can you do') and doing it in a group can spur you on to finish the program. I'm sure quite a few folks have started doing press ups in the morning only for it to fall by the wayside after a few days. Think of it as a blend of willy waving and good exercise, and thats the reason its quite popular.
As a target and motivational tool, maybe
But for the exercise reasons stated? Not really.
Getting good at doing 100 pushups is only good for being able to do 100 pushups. And if that's the goal, just for it's own sake, then fair play.
But after a certain point, you've gone beyond the concept of working on strength or muscular development, but not far enough for endurance (nor would that really make sense for such a localised exercise, unless it had direct carry-over to some other sport or physical pursuit).
And as somebody who's been involved in physical culture (exercise, boxing, lifting weights) for decades, I hate this trendy term "core"
Were you ever hugged as a child?
Oh, just come out and ask it, FFS...
"Do you have happy memories of your childhood?"
Don't go all wimpy on the Freud thing
This is our last bastion of manly men doing manly things
Um, ok, then.
Thing is, though, it's not that manly, really, is it? Given that practically all, here, ride manly, rough terrain, on manly, men's bikes, then 100 push-ups, isn't really that manly, man.
It's more, well, pointless really, man, in a manly way, though, of course.
please try not to burst our bubble and try and join in perhaps.
Well the squat thing - that made more sense.
Or running - say a mile in a decent time. What's a decent time, these days? I'm not expecting people to start running
out and buying sub-4 vest and shorts, like.
Or jump rope / skipping for 20 minutes - bonus points for double-unders.
Maybe you drank 10 beers last night, or ate a whole Chicken Phal without water or something....
