Interesting thing here--lots of the guys in this side of the house have been doing it for years and are absolutely solid, a few of us are not only older but also beginners--like me just 4 months into lifting weights.
My thoughts on this, and definitely not advice ! is to think of what you are doing as a SMART project i.e
So not so much " know where you are trying to go" ie having a clear goal, but also having a measurement tool so that you know if you are getting there and whether what you want is realistic over the time frame that you can give it.
For me my mantra has been ' lighter faster fitter stronger' weight (and body fat) relatively easy to measure and set realistic goals of fat loss, stronger in that pbs are measureable as is overall workload, faster --that my 1.5 mile time is still coming down etc.
From this i guess that waht i would be asking you is :
Do you know where you are going ?
Does your programme match those goals ?
Are you achieving your goals ?
If your programme is working then why change ?
Also if you are where i think you are (i may be wrong) ie a beginner then should not the focus be on :
Simplicity--just the big compound movements
Workload--just lifting em up and putting em down !!!
Well thats me done --over to the experienced guys .
