M51, 154lbs, 5’5 - Struggling with aging. Really want to get back into exercising, but the last two years have been so emotionally and physically draining.
It took me until my 50s to stop being self-conscious about my slender body and skinny arms. Exercising more helped a bit but it was mostly in my head. My advice - love yourself now! (The sign was for a Twitter pro-nudity campaign)
