There is also this whole puzzle solving aspect to rock climbing that I was unaware of before I started climbing. You can mostly brute force your way through a route if you are strong enough but there is always a more efficient way to do it that uses a fraction of the energy. Figuring out the right way to do a route is very satisfying to my inner nerd.
Still, that's not taking away from running, many people really enjoy it and there is no denying it a cheap way to get fit.
- all you need is a pair of decent trainers and shorts
- you don't need a partner
- you make obvious and steady progress
- most people unused to exercise need to work on cardiovascular stuff, not six packs
- you get to go outside, not stuck inside a hall or somewhere
That's subjective; I like running outside. It lets me clear my mind like no other form of exercise. (I hate running int he gym, though)
> it destroys your knees
Only if you do it wrong. Unfortunately, 99.9% of the people do it wrong. I had started to develop some knee pains (only while running) after a healed knee injury. And then I discovered the Vibram Five Fingers, and after two weeks the knee pains were gone for good.
They take a while to get used to, but they're worth it.
tl;dr run with an impact front-to-back, toe-to-heel.
front-to-back toe-to-heel is the key. The vibram is a way to get there.
The other important feature is "high-resolution" impact transfer - you need precise ground feedback for your muscles to compensate for an uneven terrain.
If you have (as an extreme absurd case) a super-hard graphite/plexiglass sole, then you have no cushioning, but are not likely to avoid delivering impacts to your knees even if you run on the balls of your feet.
Supposedly, Vivo Barefoot, Nike Free and Newton are as good. But I only have experience with the Vibram FiveFingers, which is why I recommended it.
> I just couldn't buy into having plastic between my toes
Me neither, but I just had to try, and I actually like it, even though I don't like "toe socks" inside a regular sneaker.
> or not having option of wearing some liner/socks
There are injinji socks; but I prefer the VFFs unsocked if I can properly wash and dry them (I use socks when I don't have wash-and-dry facilities).
> since mine look more "normal" or let's say less "goofy" I can confidently wear them in any environment.
That's a definite plus. (On the other hand, if you're looking for a conversation starter, the vibrams are hard to beat!)
Most forms of exercise will not give you a visible sixpack. The biggest thing that matters for a sixpack is body fat %, which requires a healthy diet more than anything else.
As for running, I HATE running for any significant amount of time, and I chalk this up partially to my body-type - I'm very good with short sprints and have large muscle mass in my legs, which is the opposite of most serious [distance] runners who have leaner legs, but similar to track stars who do the 100M and such.
At the moment I usually walk up, across and down a few floors in my building.
This is a myth.

The only downside is that it won't actually get you fit in the traditional sense. I can pull into a front lever using two fingertips, but I can't run a mile to save my life.
Still, it's exercise that you'll actually do. And unless you live in Nebraska, there's a climbing gym within a 20 minute drive of you right this minute.
Continuous bouldering again is a great way to work your cardiovascular while also stimulating your core. Slow top roping on the other hand won't be the same.
As seems to be the grandparents goal, you will definitely get a sixpack from rock climbing.
And FWIW, I've been climbing 2 times/week for 3 years now and have no where near a six-pack :)
Also the only way to have a six pack is have low body fat, one of the many ways to achieve that is through running.
I don't think one should assume exercise means running but your points against running are wrong as well.
