I weigh about 175 to 180 lbs I am 6'2 188 cm at age 17 How much should I be able to bench press and curl with ONE arm 10 reps each?

okay,. none of that really matters, there are guys out there that are 150 that can bench over 200 pounds and guys out there that are 300 pounds that coulde barely lift 100 pounds. Its all about your training and nutrition.
