Sigtech, it depends, I vary my workouts every 2-3 weeks, going from strenght to "endurance" lifting. Right now i'm in a strenght phase so I'm doing 5x5 rep max set/reps. So I start with my 5 rep max weight and do that 5 times per set, it should work so that you can't lift 5 times or your fourth or fifth sets. You should look like (for example) 200 x5, 200x5, 200x5, 200x4, 200x3. If you can lift 5x for each set, then that weight is too lite. So my split is like this now,
Mon - Incline DB Bench Press & Incline Bicep Curl
Tues -Narrow Stance Squat & Calf Press in a press machine
Wed - Off
Thu - Pull Ups & Dips
Fri - Deadlift & Standing DB military press.
During "endurance" phases ( I quotate endurance because I don't like to refer to it that way, but I don't know how else to express it.) I lower the weight by about 10-15% and up the reps to 12 and the sets down to 4 so the scheme is 4x12. Also during this phase I like to do full body workouts. My fav routine for this is "hybrids" where you do a mixed bag of things and it's on a 5 day split so MWF I do this;
BBell Hangclean/Front Squat/Mil Press
Romanian Deadlift/Bent over row
Lat Pulldown >SuperSet 1 set of pulldowns, 1 set of chinups
Chinups>Superset
Db Incline Piston Press
Ab Circuit - Hanging Leg Raise, Oblique Swiss Ball Crunch, Plank, Cable Crunch
ON Tues/Thursday
Barbell split squat/overhead Press
Reverse Pushup>Superset 1 set of reverse pushups 1 set of dips
Dip>Superset
DB Lunge/Hammer Curl
Ab Circuit - Hanging Leg Raise, Oblique Swiss Ball Crunch, Plank, Cable Crunch
I have tons of programs if you want some.
