I got high cholesterol, and I am in risk of hearth attack. Never had covid, just poor health due to prolonged lockdowns and closed gyms.
It is really interesting to see this mental gymnastics, if someone is fat, gets virus and dies, it is "the plague". But here we have dozen people talking about "personal responsibility".
b) Some of the toughest workouts I’ve done were inside. You need to stop being so close minded.
Masks do not restrict oxygen flow, there are several studies to prove it! It is perfectly safe to wear double mask for entire day at work or at school!
I also like to do tough workouts inside, at gym! I do not have gear or space at home.
The other commenters are right in saying that there are excuses, and you seem to be full of them.
I agree about the gym - you can’t replace it at home unless you’re seriously rich, like many tens of millions of net worth. My gym has pools, lots of heavy weights, many odds and ends and equipment you’d never buy.
I can get a vastly better workout there than by doing pushups at home.
For various reasons, I don’t run, which leaves cycling and swimming for cardio. I also like to lift heavy - this means a large variety and quantity of weight. I need a gym.
