Physical training w/ only bodyweight

[Draco771]

I'm having difficulties getting back on track with my normal physical training schedule, due to a shoulder injury I suffered a couple weeks ago, which is now finally getting back on track.

My stomach has gotten fatter, and my arm size has decreased...

I was wondering what kind of workout routine could I do to get back into my normal workout routine. My normal workout routine prior to my shoulder injury was:
(for total reps done)
150 push-ups (5 sets of 20, and two sets of 25)
200 crunches w/ legs 90 degrees on the ground (no stopping, one full set)
100 sit-ups (press for under 3 minutes)
50 squats X 3 (1 set Squats w/hands between legs, touching ground behind heels when reach the bottom, 1 set w/ hands facing forward, and 1 set with arms facing straight behind back)
1-2 mile run pressing for 8 Min pace.
And 60 additonal push-ups (20 w/ arms wide, 20 w/hands close, and 20 w/ legs on table)
and 40 shoulder dashes (two sets of 20).

What could I do to get back on track with this? My shoulder screwed me bad, right now, I'm lucky to do 17 push-ups w/out my shoulder going AWOL.

Running I can get back on track with (hopefully)... But it's the other things...

Any advice/help anyone is willing to give me would be great.

I don't have access to any weights, nor money to purchase a fancy book, so anything that would be all bodyweight would be great.

Thank you for reading this, and any help you're willing to give.

I've looked at all the other threads, and they are all book advertisements... (no disrespect etc. intended by that statement, just they normally mention some book to go and buy...)

Thank you.
