Question 1 : I can lift between 15 and 25 lbs. When I lift 15 I can do curls 10 times, feeling a little bit tired by the 10th time, and I normally do this 5 times in sets of 10. I can lift 25 lbs, but I get tired after about 5 curls for both arms. Once I reach my 5th set I can barely do 4 curls. Which set up should I stick with? I want to get bigger and dont care about strength endurance or w/e. Question 2 : I am also working on abs and they have come along way. I think im supposed to eat more in order to get bigger (such as arms and chest), but I want to also get a six pack, and in order to do this you need to have not much body fat. So should I eat a lot or not? For whatever its worth I drink protein powder and dont eat junk or drink soda.
