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)
40(f) - 130lbs (ish) 5ft 7. Big thighs, small boobs and cellulite. I accept it all, embrace it all and love it all! I haven't always but I do love my body flaws and all xx
