^This is the kind of thing you should've figured out before you started cycling (not TRT, but cycling) back in 2013.
You can workout every day. You can even train full body every day. The question is, do you need to, depending on your goals and current conditioning.
Asking how many exercises you should do is like asking how much fat you should eat. It's just one factor that you're trying to look at irrespective of a lot of legitimate variables. So, I'll give a broad answer: 2-4. You should definitely do 2-4 exercises per bodypart.
