Me: 15 years old (16 in about a week), 6'4", 230 lbs (about 35-40 lbs fat) 1: Whenever I start benching for the day, the first 5-6 reps (125 lbs) cause a really sharp pain my my upper arm. Not the normal weight lifting pain, this feels more like someone if trying to jam a pencil into my arm. My hands are about 20" apart of the bar, and I lower it to about 2-3 inches above my chest. Is this normal? Is there anything I can do about it? 2: I've been benching (stared at 120, now 125, about to go to 130) and curling (started at 60, now 70) for the past 2 weeks, but since about a week ago, I no longer feel soreness in my arms the next morning, though whenever I'm lifting, I feel that I'm pushing myself as hard as I can. Is this normal, or am I not stressing my muscles enough?
