Ok, that makes sense and sounds good
okay. Now you have to plug in some variables.
First, before picking exercises. Look at sets and reps.
I would suggest something like this:
day1- 3 sets x 8 reps (your intensity day); RI= 60sec
day2- 2 sets x 15 reps (your back off day); RI= 30sec
day3- 3 sets x 12 reps (your volume day); RI= 45sec
so, no matter what you do on those days (either push or pull) you are going to perform those rep ranges. the reps are high because you need to start back up again and get back in the groove and let your muscles and conective tissue get used to training. the 8 rep sets should be done with more of your 10RM. You don't want to push to failure. Instead, try and make small gains over an extended period of time. If you can not hang with those rest intervals off the bat, add 15-30sec to them, so 60sec will become 75-90sec, etc....The rest is important. I know you want to push yourself and go all out but be patient.
Okay, so now you have a skeleton of what is going to happen.
Then you have to think about what you want to do exercise wise on those days.
You can have an "A" day, which is your push workout and a "B" day, which is your pull workout.
Initially, you want to start simple and with low volume and then build up. So, go with just one A workout (push) and one B workout (pull). After a few weeks you can have two different push workouts (A1 and A2) and train them every other one, and the same for B workouts. But right now just start with one of each.
So, something like this...
Workout A:
warm up
1a) Split Squat
1b) DB bench press
2a) single leg leg press (I hate this execise but I know you like it

)
2b) overhead press
3a) tricep pressdown
3b) DB lateral raise
4a) planks
4b) stability ball jacknives
4c) external rotators
The goal is to get to the point where you only take the rest interval after exercise "b". But, you might have to start out by doing exercise "a", rest, "b", rest and repeat. As you can see. There isn't much there. 2 supersets of big compound movements, one super set of single joint exercises and then one tri-set of core and finishing with some rotators. Once you get solid with this, the goal would be to either move to a more intense total body workout OR to add in a "c" exericise and since this is a push day, it would be a light pull (for shoulder balance). So, you might do:
1a) split squat
1b) DB bench press
1c) supine row
1a and 1b are 3 sets x 8 reps
1c is 3 sets x 15 reps
Now, after that above (it should take you about 30min.), you do some conditioning. Maybe something like this:
Rowing machine
300meter intervals; 60sec rest between each
maybe start with 2 or 3 of them for the first two weeks and then bump it up to 3 or 4 of them for the next two weeks. try and keep the pace even and at about a level of 7-8 on a Rate of Preceived Exertion (RPE) scale. That will ensure that you can recover between sets and give a good power output. After a few weeks of building a base, you can do something like intervals 1-3 are a 7-8RPE, and then leves 4 and 5 are balls to the wall 10RPE....but, don't start with that and don't start by going all out. Ease into things.
For a B workout, something like this:
Workout B
warm up
1a) RDL
1b) 1-arm DB row
2a) step up
2b) RG pulldown
3a) bicep curls
3b) cable reverse flye
4a) side plank
4b) reverse crunches
4c) YTA
Then move onto conditioning....Maybe something like:
Versa Climber intervals:
60sec on; 60sec off
again, start low, maybe with 3-4 intervals and build up over weeks.
that is just a loose idea of what to do. Now, you would plug this in and figure out the final variable, which is rep tempo. Then you have everything covered:
sets
reps
intensity
rest interval
