I've been lifting weights for almost five years now but I've never really committed long enough to one particular routine. Whilst I have gotten a bit stronger (up from 40 kg on my 5RM for squats to 70 kg for example) I haven't made the sort of strength increases a beginner is apparently supposed to with consistent training.
So with this in mind, should I be running a beginner's program like Starting Strength? Or have I passed the period of time where that sort of program would be beneficial? I get a bit confused as to whether I'm a beginner by how long I've been training or by lack of progress.
Of course I'm sure it's quite possible I'm reading far too much into this beginners/intermediates classification for workout programs and it makes no difference and I should just pick one I like the look of and go with it.
I don't know if it makes any difference but I'm 32 years old, 165 cm tall, 29 inch waist, 10 stone five lbs, male.
