I liked most of the content from AthleanX. Here’s a body weight highlight real: https://www.youtube.com/watch?v=xKNIYblazQg

The host is informative without being too bro-y. He also talks about the physiology behind muscle movements which I liked.

The start to my routine was just alternating between a push day, pull day, and legs/cardio day with all body weight. I also worked in core exercise each day because I knew my abs were very weak.

For the first two months I really couldn’t do much beyond body weight. Once my own weight wasn’t making me sore anymore, I layered on the bands.

Sample push day: 3 x 12 tricep push-ups https://www.youtube.com/watch?v=rrq4_y_5vnA 3 x 12 wide grip push ups https://www.youtube.com/watch?v=rr6eFNNDQdU 3 x 12 pike push-ups (shoulders) https://www.youtube.com/watch?v=sposDXWEB0A

Push-ups with a hold for 3 seconds

With bands: Chest press https://www.youtube.com/watch?v=j3ccNPK-P4U Triceps https://www.youtube.com/watch?v=vCJaO-hCO2M

Pull day - tough to do without bands or a bar: 3 x 12 Chin-ups (fingers facing you) 3 x 12 pull ups (fingers away from you) Then I used a 5 gallon water jug for one arm dumbbell rows

Bands: This is a good video on back exercises for the bands https://www.youtube.com/watch?v=1-9f_tULVVo

Happy to answer more questions. I’m admittedly not a pro, but I’ve definitely got stronger without getting hurt using the above. My main recommendation would be to just start with your own body weight and get into the habit.

I've picked up good ideas for bodyweight exercises from Redefining Strength:

I also like Animal Flow, which I've been doing for nearly ten years:

Some people seem to motivate themselves to continue exercising by having a formal, day-by-day routine, and many online sources try to meet that need by offering programs with specific sequences and numbers of exercises. In my case, I found that I prefer trying out various exercises and then using what works for me. Fortunately, there are a lot of good ideas available online to choose from.

P90X is designed for at home workouts. P90X3 limits the workouts to 30 minutes.

They’re excellent. I highly recommend them. You can get more done at home than in the time it would take you to drive to the gym and park.

not a book, video or article per se but https://old.reddit.com/r/bodyweightfitness/ is a really great resource in case readers here aren't already aware of it. Their RR is a good routine to start with, but the subreddit in general contains lots of resources that are pretty useful including books, video, articles
