In the last week of 2021, I was brought to a rock climbing gym by my friends and started bouldering. It reminded me how many weak points my body has due to the lack of variety of sports I did. There are too many “missing” pieces of muscle flexibility constraints to achieve the V1 difficulty. And the bodyweight! I didn’t realize how much weight I have until I had to hang myself to the wall (my friends taught me it should not be “hang” but to use my feet to stand, however, I still couldn’t help but use too much “hang” with my arms).
