I've been doing BFL about a week now, but I can't seem to find the right starting weight so that I hit my 10 on time. If I start with a low, low weight...well, it feels TOO low, but if I start above that, I end up hitting that high point a set or two early. So, having said that, I need to ask this.....

That first set....I know Bill P. says that it should be the intensity of carrying a bag of groceries, right?? So it's a "warm-up" set, meant to just gently warm the muscles?? It always feels so easy when I do that... but some of the weights at my gym go up in 5lb increments, and for some exercises that's almost too much for me (for upper body). My lower body is strong, but the upper isn't near as tough. I sometimes find myself getting to that 9 to 9.5 before I'm ready, so I end up doing another set with the same weight because I know I'll hit my 10 too early with the next weight up.

Any way to know for sure? Is that first set or two just "getting things warmed up and going" or what?

Also... and this is weird: I wasn't sweating much today. The exercises were hard, REAL hard during the high points, but I wasn't really sweating. What's up with that? I drink tons of water, so I'm not dehydrated. On leg day I do sweat more.

Thanks in advance for the help.
