Thanks for all the feedback. First, I was a member of a gym for a lot of years and recently let it lapse. I'd just do 2-3 sets of 2-3 weight machines (varying each time) and then 30 minutes of elliptical. Not hard core but enough and plus I'm in my early 50s so even that is good for that age. But I was going less and less because it was a pain so I didn't renew. Thus, my initial idea to replace the gym with an elliptical and now a rower instead.
But as someone said, weights are good to use so now I'm thinking of also getting hand weights and doing some of that in addition to rowing. I know, real weights with benches, etc is best but I know myself and I know I'm not gonna be able to make myself do all that. From what I read you can do a fair amount with hand weights too.
So the question now is, who has used those and whaddya think? From what I read there are dumbbells where it weighs whatever it weight (10, 20, etc) and you lift it and there are barbells and free weights where you have a bar and you can add weights to it. I'm thinking of going with the latter. (I mean a short barbell you can hold in each hand.)
Yes, it takes time to take the weights on and off between different sets and that hurts cardio but I'll be getting my cardio from the rower anyway. And it seems to me that it's more versatile because you can mix and match. If you buy two 5s, two 10s and a 20 for each arm you've bought 100 pounds (50 for each arm) and can do any number up to 50 that ends in 0 or 5. OTOH if you buy dumbbells of 10, 20, 30, 40 and 50 for each arm you've bought 300 pounds (150 for each arm) and you still can't do numbers ending in 5. And you have 200 more pounds of stuff to store. So that's what I'm thinking but I'd be curious if others have experience with that.
As far as the rower goes, I did some research and I did see that the air is best, as someone in this thread noted, but I was thinking of going with magnetic because they're quieter and that make it easier to listen to the TV or a podcast (lots of good podcasts these days) and anything that makes it easier I figure I'll be more likely to do. Anyone have any experience with a magnetic rower?
I looked into the BowFlex Max thing someone mentioned but that's a couple grand and plus at this stage of life I doubt I'd get max benefit from something that advance, but thanks for the suggestion.
I've concluded on exercise that the perfect is the enemy of the good. Just doing something is good, even if you're not doing stuff that's perfect. If you kinda want to exercise but don't want to make a giant commitment to being great at it, just do something. I little is a lot better than nothing.
