If I use smart programming, and get help and coaching, how long could I expect to continue getting stronger or improving my form and so on?
We obviously can’t predict this, but we would all agree you can continue getting stronger for a while. 47 is not that old.
What I meant by “advanced” was I am expecting there comes a point where your level of time commitment makes it difficult to get enough stress in to adapt, but I also know you are insanely busy but have gotten stronger. I am wondering how that plays out. I have heard some SS coaches mention the “average” client doesn’t move beyond a certain level if training. Sorry for confusing that point.
That depends entirely on how much the “average” client cares about their training. If they travel frequently and don’t train, skip workouts, etc … then yes, they won’t make it very far over the long term. This is the context in which you hear things like “most people never make it past X phase”.
But for someone who shows up to the gym as scheduled and doesn’t miss workouts on an intelligently designed program, it’s logically impossible for them to remain “novices” or “intermediates” forever under the traditional definitions of those terms … because that would imply they’re continuing to make progress on a per-session or per-week basis … FOREVER. Eventually, as long as someone can train consistently and stay relatively healthy, everyone can become an “advanced” lifter under those recovery-based definitions (yes, regardless of whether they choose to compete or not).
Furthermore I was wondering if you still lose strength as you age, even if you keep training intelligently? If so how much do you lose?
Obviously, yes. You don’t see any 90 year-olds pulling 600 lbs. But this is a highly individual thing, and the rate and degree of strength loss depend on far too many things for us to give you a useful answer on this. It involves genetics, training history, diet, hormonal status, comorbid medical conditions, and a number of other things. I’d suggest you try to control the biggest ones you can control, namely: 1) consistent, intelligent programmed training, and 2) consistent, sufficient dietary protein and calorie intake.
