so i do a push pull routine 4-5 times a week, and my main goal is strength. i notice i tend to incorporate many different types of lifts. is that good or bad? for instance, here's an example of what i'd do for my back on pull days. one pull day i would do deadlift and face pulls. the next pull day i'd do bent over db rows and pullups. and then the next pull day i'd do deadlift and back extensions. i must do deadlift once a week, but the other 3 back lifts i'd do for my back varies depending on what's available and what i feel like doing. any benefits of doing, say, 1. just deadlift, rows, and pullups versus doing 2. deadlift, rows, pullups, facepulls, extensions, good mornings, pulldowns, etc etc etc? my first thought to this answer would be to do #1 for strength focus, and #2 for definition. not sure about this, so thoughts?
