Yes, agree with OldTimer1. Always make an exercise harder, allowing the muscle to adapt, and progress will usually follow. Also agree the ROM is relative to each of us, as are muscle inserts, bone leverage/length, etc. All points placed under the mechanics (physics) of individual lifters. Considering the height/travel of a lift, as a short vs long arm person, can also become important.
If anyone thinks that Old School workouts means only heavy compound exercises, including full body workout, they are mistaken. Systems that have been around for a generation, or so, are SS, tri, quad and giant sets, TUT, Rest Pause,drop sets, extended sets, moderate pump sets, negatives, 21's, half reps, GVT, etc. Guess you might call these modern thinking, because most top BB'ers follow these protocols every day of the week. Those BB'ers, back in he 60's & 70's weren't too bad either.
Even the very old 5X5 system (long before Bill Star made it popular) is still used today, with good results. Old school or "modern thinking" are pretty much the same, only the label has been changed. Now I plan on doing some old school standing presses to get modern results. Good Luck.
