Are you not meant to lift to failure on every set? I just read this on the starting strength FAQ:
"The way the "first day" is explained in Starting Strength, the trainee warms up with the bar, then adds a bit of weight and does a set of 5. The bar speed will be identical from set to set. Continue to add weight and do sets of 5 until the speed of the barbell begins to slow.. Keep the weight there and perform 2 more sets with this weight. That is your first "3 sets of 5" workout for that exercise."
I've always gone to failure on each set, which makes my reps look like 8/6/3 and stuff like that.......have I been doing it wrong the whole time..?!?
Also another side question... I have been doing skull crushers for triceps and calf raises for calves etc in my routine. If I switch to SS practical programming will I loose the muscles I've built doing this?
