In my split. Assuming we are on push day. I will typically start with a Bench Press. I usually do a couple of warm up sets usually ending in 1-2 reps on the final warm up set. The weight is usually 20 pounds lighter than my working set.
When i warm up this way I can usually press 5-6 reps at my working weight. 5-6 is also when I’ve pressed and realize I cannot press that weight another rep or I’ll be in deep trouble. When I do this many reps to failure, my next set is usually 3-4 reps before I feel the failing fatigued.
I recently eliminated my 20 pound difference final warm up set and noticed I added two additional reps to my working weight, but stayed the same amount of reps on my second set
Question 1 should I always train to that last rep on every set or should I be setting a goal number and pick a weight that I can press there close to fatigue but not to failure or final fatigue? 2-3 reps in the tank
Question 2 when warming up. Should I be using weight that close to my working weight? What should be a general difference?
