I have a question on how people approach warming up and stretching. This is what I currently do: 1. Warm up via cardio till I break a sweat. 2. A couple of short/light warmup sets for a exercise on the first few exercises before work sets. Optional warmups for later exercises that are lighter weight or are smaller/non-compound. 3. Stretch. Work on improving flexiblity in problem areas. My question is. Should I insert some stretching before #1 and #2? If so, what kind, method? Also, I don't usually work on non problem area in #3. Should I make an effort to stretch all areas? Is stretching an area directly after an exercise better? I feel that I lose focus on working out if I do that. Thanks for any help.
