You absolutely can and you definitely do not need to be ripped or even vaguely strong to get started climbing. I really enjoy going with the TV even though we’re at completely different levels (i go 3 times a week, she’s maybe twice a month) because there’s always easier and harder stuff nearby. Contrast that to doing something like running with a big ability gap.
If you go to any climbing gym you’ll find a massive range of bodies, ages, and abilities in a fantastically supportive environment. Everyone’s challenge is the same whether you’re huffing and puffing up an ‘easy’ route or busting out a one-finger pull-up.
And then if you choose to take it outdoors it’s an amazing way of experiencing nature
