general climbing
This is a very general question. Is it for bouldering? Sport climbing?
There is too much missing information in the question to be able to actually answer it accurately, but, in any case, it would most likely depend on your experience, technique, strength, and how determined you are.
Try to find the next best thing that you do have. Do you have a spray wall? If not, do you have an overhanging wall that you can make up boulders on using the existing holds?
Otherwise, I would just make up boulders anywhere in the gym and try to make them system-board-like.
It can be pretty difficult and hard an you, but it really depends on how good you are at listening to your body and giving it the amount of rest it needs.
If you can do this well enough, climbing won't be that hard on you, it will just be hard in general, as a sport.
How do you define a good body? Climbing can definitely make you stronger, but it wont necessarily change the way you look.
But then again, it depends on your definition of a good body.
If a stronger body counts as a good body alone, then yes, climbing can give you a good body.
Climbing most likely wont, for most people:
- Cause you to lose weight
- Put on a significant amount of muscle mass and size
Of course, climbing can motivate you to make these things happen, but climbing alone usually does not cause this.
This is a really general question. It depends on a few things:
-
Why kind of climbing are you referring to?
If its bouldering, then you can climb on your own, but if sport climbing, then you require one more person to belay you. -
Why are you climbing?
Assuming the reference is to bouldering, then the question is why you are climbing. If you are climbing to just detach your mind from the day and to just be physically active, then yea, you could climb alone, and it may be better also if you just don't want to deal with people.
On the other hand, if you are bouldering with the goal of improving, then I would say both options are important for your progress. Climbing with other people, especially those that climb better than you, can really give you more insight into climbing, more ideas, betas, experience, and just more growth in general. Climbing alone is still important in my opinion though because it's when you are alone that you can actually practice all that you have learned with others.
That's my take on climbing with people vs climbing alone.
Extra point:
I personally find it quite hard to have a proper bouldering session with some friends. Instead of climbing hard routes, we end up just messing around.
