Based on what I have read in the book "Rowing Faster" (Nolte, Editor), it appears that I should be working on improving my strength, because, as the book states "strength may be holding my rowing back".
The book includes a set of strength tests, based on the weight you can do 1 rep with, naturally called 1RM tests. For my age bracket (45-49), it says I should be able to:
Squat: 1.2x body weight
Deadlift: 1.2x body weight
Bench Pull: 0.94x body weight
Now, this post may be premature, but I suspect that I will not meet these criteria. The tests take a fair amount of time, and I haven't put the effort in yet, but I will. In the mean time, I am trying to work out an optimum approach for adding weight training to my routine. I have started haphazardly, and perhaps that is the best way to proceed, but I am struggling with some questions that I would appreciate others advice and feedback on.
1. How many times per week? I initially thought 3 times per week. Andy suggested that 2x might be a better fit with the rest of the erg based training that I am doing. I think he may be right. I am finding that I am "weak as a kitten" on the day following a weight training session and have a massive case of DOMS on day 2 after. Anyone have any resources that would guide me on adapting weight training to the, err, older athlete?
2. How should I expect weight training to impact my performance in erg based training? I am OK with the idea that the short term muscle damage that is a necessary part of weight training will slow me down. That is, I am OK with it if I end up being faster than where I am now once I adapt, and taper down. The thing I am looking for is a perspective on what has happened to others that add weights. Do you see interval splits going up?
3. Low reps & Heavy vs High reps & light? I know this borders dangerously close to a religious discussion for some (See Brad Lewis, Assault on Lake whatsis? for more on that one), but I'd like to know any practical experience for folks who have used weights to successfully get faster on the water or on the erg.
4. Plyometrics? Almost put myself out of commission for about a month by stupidly going at this a year ago, but I could see why explosive strength has a value. Should I be thinking this way?
5. Recommended resources? I have found 2 that specifically address strength training for rowing. The first is the chapter in the "Rowing Faster" that made me feel inadequate in the first place

I know it's a lot of questions, but I thought capturing answers to these topics could provide value to a number of forum members.
Thanks in Advance.
