Most Helpful Girl
As a female who has many female friends (and we all share our thoughts on guys) I can honestly say that being athletic isn't as important as being healthy, I'm not gonna deny I wouldn't like staring at rock hard abs but at the end what matters is the personality and both myself as well as my friends have dated our fair share of guys who didn't have abs and it was never a big deal, any girl who deserves you needs to be able to look past the surface. So don't feel bad about yourself because confidence is sexier than any 6 pack so self hating will only be a turnoff. Also if you really want a bit of muscle I recommend much protein and for your body to absorb the most of it you need to have it after you exercise not before (in case you didn't know.) Also don't overwork yourself. I have seen even the most unlikely candidates find true love. Also you can't stress about something like this there's no way you're not going to find someone so stop scaring yourself.

If you're that desperate for female approval you will still not get it even if you manage to get "rock hard abs". Desperation is not desireable no matter how attractive you are. Come to terms with the fact that you're not physically attractive. And guess what 98% of the worlds population aren't the ideal either so you're not alone.
