Legs!!! No just kidding...just wanted to quote about every other person in the gym anymore. I think I would agree that biceps is likely the most dreaded, not arms just biceps for some reason. Love the pump from legs, shoulders, and back. Although I pay the horrible price later in the day, each time, after leg day no matter if its a high rep, high weight, mid both, etc...legs just lock up and Im stuck in the baby position the rest of the evening.
calves. I dont have the none growth issue many have my calves grow fine, but the way I train them they cramp like a mother F--er. If I make it through the workout with no craps I cramp at night when Im asleep. Worst.
I would say now it's shoulders becuase I have a bad shoulder so all I can do us rehab. I used to love training shoulders... part of the reason my shoulder is so bad now...just because you can lift a certaint amount of weight...doesn't mean you should. I used to shoulder press really heavy weight. After a certain point I was increasing weight but my shoulders weren't getting any bigger, but I kept going heavier. Guess it was an ego thing where I just enjoyed lifting big dumbells above my head. Whish I stopped at 80's, instead I would do 80s as my heavy warm up set....it didn't count as one of my working sets...
Like SAD said, I hate that I have to spend so much time doing rehab, steerching, etc
I love training legs, but yea, it's no question that it sucks training them when you have injuries, or running on low sleep. Actually every body part sucks training when you are injured, aging, or tired, lol.
I hate (training) my Biceps. I had a pretty bad Radius fracture from a fight (forearm stomped on by boot) as a teen. The Biceps heads each insert there so my left Bicep barely works when rotated any way other than Hammer Curls. The right one is by no means huge but there is a noticeable difference in size and particularly the peaks. They suck compared to my Delts and Triceps and look "overpowered" by my back and chest. Which is oddly the opposite of 98% of the gym which is all arm no torso lol.
Nothing jumps out at me. I like trying to improve everything. If anything, I hate training calves because of some nerve damage that obstructs growth. It sucks, but there's nothing I can do about it. No viable nerves in certain areas, no growth.
