My squat is 225x4
Bench is 300x1
Deadlift 405
Dumbell shoulder press 100 lb dumbells x6-8
Barbell Rows is 245x5ish

I'm pretty stuck now at these weights. For the first time I'm actually getting really frustrated and kinda sad. I feel like not doing this anymore. I'm still 295-300 lbs. I still have ****ty chin-ups.

What it feels like is my newbie gains are done. I'm at a crossroads where I either have to lose weight and strength. or gain 20 pounds and gain strength.

I hate whining. My questions are...
Can you tell when you're done with your newbie gains? How long did it take you to get over the fact that you're not going to PR every other week? What keeps you going?
