Just remember not to go overboard on the protein: Check your weight, age, and activity level to determine how much protein you should actually have (somewhere between 10% to 35% of your total calories). Too much or too little can have bad outcomes.
FYI- There’s a TC Android client and it’s pretty good. Interface is dated but function is more important than form in my opinion.
I’d probably say Steam or VLC player.
Start off slower, pace yourself, and also maybe supplement with something else that’s low impact like bicycling or swimming (both can be great cardio). Don’t forget to add strength training days and rest days too.
Eating right and getting adequate sleep is also going to help a lot.
Yes.
