To join a gym?

Depends on your goals. Exercise is a great way to keep fit and healthy, especially strength training. After your 30s your muscle mass declines with age unless you strength train, it’s a use it or lose it situation.

Exercise is not a great tool for weight loss though. It’s kind of like going swimming as a way of getting a wash. It’s better than nothing, but there are far more efficient ways of achieving that goal. I.e. sort out your nutrition.

I would highly recommend small group style classes. Much easier to want to go back if you have friendly faces and an instructor safely guiding you, rather than walking into a room full of exercise bikes and weights not knowing what to do.
I’m
naturally lazy but once I force myself to go regularly and build the habit it just becomes part of your life, same as brushing your teeth or doing the grocery shopping does.

Please note I have not lost any weight as I probably eat too much but I don't put it on now. So do look at your diet if it's weight loss you want.

I'm 63 and go 4 times a week and lift heavy. I have a PT once a week. The people who go to the gym are lovely. Quite a lot of older ones and about 5 of my neighbours go which is fun as we encourage each other.
It's "The gym group" I go to and pay £20 a month. I can walk there in under 10 minutes which is great!

I am a total gym convert. At 49 i wanted to develop my flexibility and strength. The lad at the gym did a program for me and i have been going multiple times a week to lift weights and, and this is a real shocker for me, enjoying it!! It is hard, but in a fun way!! I have always been chubby and peri has piled on the pounds but because I am heavy I am also strong and looking forward to getting stronger. Make sure you get a proper program done! Good luck!

What @LiveLaughGoblin said. I started going to my local gym at 50, had some sessions with a woman PT who drew up a cardio & strength training plan for me & its been brilliant.

Give it a go! The best thing you can do is get a PT for a month or so and learn how to lift weights. It so so important for women to maintain muscle and bone mass as we get older.

Your legs and back are the biggest muscle groups in the body and if they are strong then it will fire up your whole metabolism and help with the muffin top as well.
