i have a friend who 's been weight lifting with me for years now and he looks better than me . i wish i had his genetics ! oh , i totally understand . it 's frustrating when you feel like you 're putting in the same effort ( or more ! ) and it works better for other people . it sure is frustrating , but i ca n't say i have n't made great progress myself . but his progress is insane ! well , it 's good that at least you 're making progress ! it would be crazy frustrating if you were n't . congrats on your hard work paying off .
His friend's exceptional physical progress and superior genetics triggered feelings of jealousy.
