Today I did this for chest (working sets):
1. Bench Press 3x5 on pretty intense weight. The last set I would have failed on the fifth rep without a spotter.
2. Dips 3x5 on bodyweight. Probably would have failed at 7 or 8 im guessing.
3. Incline DB Press 3x5. Last two sets were really intense, almost failed on the third.
Now I'm usually not sore to the touch if i rest three days between workouts. Does this mean I can lift chest every four days?
