I work out at the gym three to four times a week. My muscle mass has declined and my strength has declined. I have to be a bit careful because what I could do three months ago is now too heavy, I did make a mistake of picking a weight I used to use and nearly pulled my arms off

, by the way I do not do muscle building work, just flex and cardio. Strength and definition have gone mainly in the upper torso. My legs seem to be fine and maintain their strength. My flexibility hasn't really changed.
There has been one massive change this week. One of the female trainers came to me and asked if she could review my program. Previously only the male trainers ever reviewed me. And I've never seen a guy having their program reviewed by a female trainer. Oh well, they must be short of trainers

BTW keep working out. It really helps in several areas, including, for me, depression.
