Bodyweight routine (no post-workout soreness?)

[barna284]

I recently started a small bodyweight training routine involving pull-ups, diamond push-ups, crunches, extensions and wide push-ups. After the third set of each excercise, I´m pretty much spent, sometimes not reaching the target reps. However, I´ve been experiencing zero post-workout soreness in my muscles. I am afraid I may be training endurance instead of strength.

All the arm excercises are relatively low reps (5 pull-ups, 8-12 for diamond and wide push-ups) and abs/extensions are about 20 reps. Could I be gaining strength and not experiencing any post-workout soreness?
