Yesterday I did my first 12 reps ever on a Smith Machine at my gym. I was shown the right way to do the squats I’d been doing using a Swiss Ball for about 2 months, so I knew the form by using the ball had no ill effects on me, so I decided to try. The bar-bell is 45 lbs, but it was explained how I wouldn’t feel the full weight of that by using the SM. I did 12 reps only and really felt tired after that
but loved doing them that way.
Today I will do more of my upper body using the “cables” which have been my fave since I joined the gym about 3 months ago come the 15th of this month. I do 4 exercises on that, but the arm-curls I started using free-weights.
Anyone else starting out with free-weights? I have some progress I can see, especially in my arms and shoulders, I don’t really see a lot in my back muscles. My legs are getting more toned, than my walking has shown, but the walking got me into weights/squats easier. I’m 69 and this is the first time in my life I stuck to a workout plan, not perfectly but not wasting my gym membership. Definitely room for improvement on getting there at the the least 3 times a week, not just the 2 in 7 days 
Right now walking upstairs to take a nap is about all I can handle.
I had a weight bench and 100 lbs of weights, gave them away because I wasn’t using them last Summer, arggg! But for me, I think it’s good I’ve used the gym because I’m retired and downright unsociable about going out of the house/apt. Once I get out there I’m my old self, friendly, smiling, chatting if someone wants to, but I so keep my distance, physically and mentally/emotionally. I’m always relieved to get back to my little mole-hole, LOL!
I know if I was married I’d want my “me time”. I still hope to meet someone to share my life with but have to maintain some of my independence and my mate would have to be pretty much the same in that area 
I just don’t have enough weights for that, probably… (I have but I won’t take apart my barbell for it, I am lazy. There was some talking about their weights somewhere lately, well my barbell weighs only 7.5kg. It was heavy enough for me, I mean, 10-12 kg would have been better but 15kg would have been too much in the beginning).
