When I 1st started training I hated bench press - I did alot of 5x5 back in the day but still neglected bench press - so it honestly prob took me 6,7 years to bench my bodyweight - but from there added on alot of kg's fast - now it is one of my fav lifts.
One of my close friends has always been a total freak in the gym and was benching around 140-160kgs at 17-18yrs old weighing about 90-100kgs....just insane....
