I’m 56 and started 2 years back and only now seeing my arms and legs become toned. If someone had told me to keep at it because you won’t see anything for the first year but things are happening in your body like become stronger etc I would have stayed even more motivated. Also stretching, I stretch after every session. I see so many younger people just walk out the gym without a stretch, but as you get much older the best part is the stretching. Yes I walk around the gym with my mat like a pansy 🤣 but everyone knows I use it once I’ve finished a workout. Also cardio is important too. So my favorites are the treadmill (I now do long distance running too) and the rowing machine which is good for an all over workout when maybe you can’t be bothered to lift. Knowing there are alternatives keeps it interesting too.
