https://darebee.com is another good site. They have lots of videos explaining various exercises. Just make sure you start with the entry-level exercises to slowly build up your strength.

I'd even recommend to not worry so much about timing your workouts as this causes too much stress, just focus on the exercises themselves in the beginning to make sure you do them properly.

This app may be useful to you. I've used it for about 6 months and have been pretty happy with it. You can customize what equipment you have available so that it builds you a workout based on that. On the other side, you can look at what equipment it lists and determine what you want to buy.

I'm not sure I'd personally suggest that hoovering the house is an "excellent" form of exercise, but at least they didn't blindly assume the person was going to the gym purely because they were not aware how to exercise outside of it. Perhaps the community aspect of their gym is what attracts them. None of the replies actualy answer the original question of are gyms are a particularly bad place to go. I would suggest they absolutely are a bad idea as they involve a lot of air conditioning and a lot of shared surfaces. And also a lot of coughing even at the best of the times.
