Some people do 300 pushups a day so the body can take a fair bit. Maybe only 1 or 2 exercises for high reps though. David Goggins said he did 200 to 300 reps to get fit in the early days but I dont know his program entirely.
Let's say I did
Seated rows 2 x 50 reps
Lat pull downs 2 x 50 reps
Incline dumbell press 2 x 30 reps
Military press 1 x 30 reps
Shrugs 2 x 30 reps
Light weights once a day
