Yes, I suppose I could have given you more info. So here goes...
I'm a 45 year old ectomorph, started working out with weights about a year and a half ago, and recently began HST (tomorrow is my final day of 15s). I'm in good shape for my demographic, but I've had a recent knee surgery, so I'm only able to do squats and deads with very light weights to ease the knee back into it.
Regarding my question - it was a pre-emptive strike. I'm still a few weeks away from my 5RM, but I'm trying to prepare myself for the possibility of my joints not being happy. That may not happen, but just in case...
The reason I asked about only one week of 5RM is that sometimes a simple alternative can provide an effective workout AND protect one's middle aged joints. For example, my shoulders are very vulnerable to the bench press. Fortunately, I've found that hammer gripping dumbbells presents no problem at all. That's the only way I bench now.
Lol, I'm not familiar with MaxStim so I'll look it up as soon as I post this. However, if you have a link feel free to post it.
Thanks again, guys.
