This is abstract and will probably get many answers but I need to hear some commentary on the topic. I am currently running SS, a second time because I had a hand injury this summer and lost a lot of strength during the healing process. What I have noticed: I wait a long time between sets(work sets), often ~5 minutes. If I rush myself I cannot complete the reps in the second and third work set. I have heard people say SS can be done in 30 minutes. No fucking way... It takes me more like 90 minutes from the first warm-up of Squats to the last rep of deadlifts. If you do power cleans it would take even longer due to the 3x5 instead of 5x3(currently doing chins instead, due to initial hand weakness). Here's where my issue is. I have been lifting with a friend the last few Saturdays in a commercial style gym and I notice almost no one takes long breaks between sets. I'm not sure what program (if any) most of these guys are running, but what I do notice is they can bang out 4 exercises in the time it takes me to do just one. Also I seem to be pretty much tired out after my 90 minutes or so of lifting, is this because my psyche knows that I "plan" to quit after my last set of whatever and I get the sense of completion afterwards? I have thought about adding curls or neck raises, or abs, something complimentary to the workout but by the time I finish the SS stuff I never feel like doing it. I was wondering if this is normal, to have such big rests and be tired out after the big 3, and if this is to my detriment? Would I be better off to run around and do 12 things like these guys are doing?
