I have been going to the gym since last seven years.
My friends at the gym do more than 15 repetitions per set.
I am not comparing with them, but I don't understand why can't I do more that 15 repetition of biceps, no matter what weight I take be it 20 or 25 lbs.
I normally use 50 lbs for my decline bench with 15 repetition per set and 20 repetitions with 40 or 45 pounds.
After 12 or 13 repetitions of biceps, I feel like I can't lift my hand.
I have also ensured that I am doing it in a right weight.
My trainer says I need to increase my diet.
I eat 2 chapatis with some vegetables in the breakfast, then at the lunch, at evening breakfast and at dinner.
chapatis has roughly 50 - 60 calories which is made of wheat.
Is it that my arms are weaker than the rest of the body ?
