what sort fo rep range are you doing Gaz?
I was told that between 8-12 for 3 sets was wrong in my last thread so what do you suggest for push/pull/legs ?
Depends on what your goals are really, but i will say this - There is no golden rep range for ANY goal. Louie Simmons (i think it was him) said "Everything works, but nothing works forever" and this is very true.
The best rep range is cycling between MULTIPLE rep ranges. This is called periodization, and is one of the most useful, and beneficial things you can ever learn to utilize. Basically, periodization is the planned fluctuation of one or more training variables to provide a unique stimulus.
There are far too many ways to list, i think there are probably unlimited combinations of all training variables, but look at everything you can change:
Exercises
Rest Intervals
Sets
Reps
Rep Tempo
Density
Intensity
Frequency
Volume
Training Split
And there are probably a few more that ive forgotten.
If you can set up a program that plans the fluctuations of these variables well, you are guaranteed results.
Cowpimp wrote some awesome stuff on Periodization in his stickies in the training forum, and if you pick a handful of journals and read through them youll see periodization in many flavours and colours in use in pretty much all of them.
So yeah, 3x12 is wrong, but only because thats ALL you were programming to do.
Atm because im coming off injury, im taking it slow and just using 2x12-14 at the moment. This may seem hypocritical when reading all the stuff i put above, but rules are made to be broken and injury and the early stages of training are two exceptions to this periodization rule.
The reason being that you need to learn/re-learn proper motor patterns, and raise your conditioning to a base level before you start to think about going nuts with heavier weights.
I wont be going below my 8RM for a good 6-8 months. Maybe even longer. Human tissue is a bitch when its injured

Hope any of that helped in some way.
