First time to the gym today

I've never been to a gym, either. It's a bit costly for me at the moment and I also have felt like you before where I assume I won't fit in and would feel stupid... I would prefer to have equipment in my own home because I think I'd be better motivated if it were right there in front of me, but it's expensive to get good gym equipment! Glad you decided to venture out and face some of your fears. Best wishes.

Well done for joining up! I'm a qualified gym instructor and believe me, no age is too old to start getting fitter. I had to stop teaching as, once I hit the menopause, I found all sorts of joint aches and ligament problems getting in the way - but that's the trouble with teaching. To earn money we have to break our own rules about overtraining! I'm 50 and still exercise for pleasure. Not as much as I used to, but I still try to get to the gym 3 -5 times a week. I get edgy if I don't exercise. I enjoy weight training and cardio machines, but I hate running so I avoid the treadmills. Best way to start is to follow a set program. As you get fitter you can increase the amount of exercise you do. I'm assuming you have qualified professionals at your gym who will be able to guide you towards exercises suitable for your age. As well as the gym, try classes - they can be a lot of fun. There are plenty of people here who can help you with any questions you have. Have fun!
