I found this story SUPER inspiring & wanted to share. This is a post from this morning, on the Starting Strength IG account.
Below, I’ve added in the weights in American Units 
I’d like to know her height. She seems quite petite, weighing only 119 pounds after three years of barbell training. I’ve got at least 20-25 pounds on her, and I’m 5’6"
You can start at any age, and reap HUGE benefits.

After Patricia was diagnosed with osteoporosis, her general practitioner gave her 2 recommendations - medication or barbell strength training. Having been on medication for years with no results, she decided to give strength training a try and walked into our gym about 3 years ago - age 62 with zero experience lifting barbells.
On the first session, we found a weight that was suitable for her and slowly increased the weight over time. After a year of training, she went back for another bone scan and the results showed that she’s out of the osteoporosis range and is now just osteopenic.
Encouraged by the results and feeling the benefits of being strong, she kept on training. While she was happy to keep training, she thought that her progress would plateau at some point. Boy, was she mistaken about that. As she got stronger, her strength gains began to slow down but that was expected - the stronger you get, the more effort and time is required to drive progress. Even though she started at age 62 and never lifted barbells in her life, she was able to make progress over the long term - slowly and steadily, she got stronger.
The longer she trained, the more into lifting she became and soon she started competing in strengthlifting and powerlifting meets. Patricia was supposed to compete in the Singapore Powerlifting Open 2020 but the meet got rescheduled. Not wanting to waste her preparations, we decided to hold a mock meet before the gym’s temporary shut down
4 days before the shut down, she squatted 66kgs [145.5#], bench pressed (paused) 38kgs [83.78#]and deadlifted 110kgs [242#]weighing in at 54kgs {119.5#!!!]at 65 years old. Patricia walked into the gym osteoporotic and in just over 3 years, managed to DEADLIFT DOUBLE HER BODYWEIGHT. If that’s not amazing, I don’t know what is
If you know of someone who thinks that they’re too old/injured etc to strength train, tag them so that they can see that it’s never too late to start.
