Not trying to hijack, but wanted to add a question with this. When I change up my rep range from say 3x10 to 5x5 I always throw a little more weight on. I have always wondered if I were doing this wrong but was always too afraid of being called an idiot. Should I keep the same weight with 5x5 as I used with 3x10? It never felt right doing those first couple sets of 5 so incredibly easy.
