Besides the treadmill, recumbent bike and elliptical, I like to use this machine for the arms, it's like pedaling a bike only you hold the handles with your hands, you can go forward or reverse and set the resistance as high as you like. I also like to use the chin-ups and dip machine, you can hold the handles above you and do chin-ups or hold the side rails and do dips, there's a step and a weight assist, so it's not nearly as hard to do as a regular unassisted chin-up.
Then I like to use the machine where you set the weight (my setting is 40lbs.) and you just pull on the handle like a rowing motion, also lat pull down, chest press, overhead press, tricep dip, etc. I have weights and a weight bench at home, but I prefer the machines, they make it a little more interesting.
Nice that your hubby is going to the gym too, my husband has no interest in going to the gym at all. He has weights and a bike at home if he wants to exercise. Lately he's been having a lot of issues with his legs and hip muscles from old injuries, so he really hasn't even been going on daily walks with me and the dog. Hoping he feels steady enough on his feet to join me again in the near future, right now he's using a cane in the house to get around.
I'm like you, I do a lot of house and yard work and have always helped my husband with projects. It is better if your strong and in good shape even to do work around the house. Good luck with the skating, I never was ice skating and as far as roller skating, just when I was a kid on the sidewalk, with the clamp on skates that had a key.
