Well here's my routine. When I reach 3x20 on all exercises I will add weight and keep reps below 10. My only equipment are 30 kg of weight ( 2x5 kg metal plates and 2x10 rubber plates) and a EZ curl bar which I don't use. I do pullups at a basketball basket which has a pull up bar welded to it and fortunately other bars on it are very thick ( I will use them in future to avoid tendonitis).
Pistol squats - 2-3x10-20 / 45
Dips - 2-3x10-20 / 45
Chinups - 2-3x10-20 / 45
Decline Pushups - 2-3x10-20 / 45 - I'm advancing towards a handstand pushup
Towel Inverted rows - 2-3x10-20 / 45
Hanging leg raises - 2-3x10-20 / 45 -working my way up to a full hanging V-up
Back extensions -2-3x10-20 / 45 -eventually, I will try glute-ham raises
I increase reps like this 7, 7, 7, next time 7, 7, 8 etc....
My current goals are: 25 pullups and 3x20 on all exercises.
