I really don’t think context changes a lot in this case. Being frustrated doesn’t make statements like this acceptable. Neither does starting the sentence with “if” or being right (which he was).
Believe me, my intention is not to attack or discredit Linus. As a SE and Linux enthusiast I have a great deal of respect for him. But this is not exclusive with acknowledging that he is just a human and has flaws like all of us.
I brought this up to show that it’s more complicated than just being “really nice but very honest”, that’s all.
You can absolutely workout at home with almost no equipment. You will need something for pull ups and that’s pretty much it. Google “calisthenics” - that’s what bodyweight exercises are called. It’s a whole world of knowledge with books, blogs and YT channels covering the topic. Many would argue that this type of exercise is actually healthier than using gym equipment.
I started doing this 4 years ago and I can highly recommend it. I hate public places like gym and I don’t like wasting time for getting there and back so exercising at home is perfect for me.
