    So I recently started P90X and Im currently doing shoulders and arms and I have noticed I have a considerably harder time with weights in my left hand than in my right arm, is this normal? Should I increase the number of reps in doing with my left or just do them evenly? Could use some tips there if anyones got em. Thx - James

    I noticed I'm weaker (and just slightly smaller in size) in my left arm when doing curls. Oddly enough I'm left handed. I've started to do a few less reps with the right side in hopes to balance it out. I'm not sure if I'm doing it the right way, but I'm notice the strength part starting to get more even.

    Normal. we are all imbalanced to some degree, certainly to start with. Keep working well, using dumbbells over barbells (then each side HAS to do the same work). It will change with time.

    Asymmetry is normal, and will fix itself over time, unless you have some congenital defect.

    Thanks guys! Puts my mind at ease a lil bit...but another question pops into my mind, is it better to use dumbells or barbells for curls? Cus im hearing conflicting information from people I know that give me tips/suggestions. Currently im using barbells 20#s in each hand doing about 30reps or more if i feel inclined to do so.

    Forgive me if im getting my wording wrong...like the name suggests....Newblet icon_redface.gif

    I've always heard (and for me personally too I've noticed) that dumbbells are better for control and they don't limit range of motion.

    It goes without saying / makes common sense that independent motion is superior for symmetry. Dumbbells allow a full range of motion, and, unlike machines, don't limit the motion through a particular axis, so they involve more stabilizers and assistors. With a full range of motion, also, comes a full stretch. A stretched muscle can be up to 30% larger than a non-stretched muscle.

    Esoteric stuff really isn't necessary and increases chance of injury. A full range of motion, under control, at the proper cadence, is what works best. 1/2 reps, partial reps, really aren't a good idea. Because you can lift more in the eccentric part of any particular movement, occasional negatives can be o.k. for a seasoned lifter, but, probably aren't a good idea for a novice. Stretching (isometrics) is essential for injury prevention and full muscle development, but doesn't increase contractile proteins. There's a number of schools of thought about how to strengthen tendons, and ligaments, and you'll have to choose which you wish to believe.

    Strength and size, are fairly independent of each other. You'll want to study muscular hypertrophy to understand this more fully.

    To fully understand this, you need to research sarcoplasmic hypertrophy. It might well be something quite different than what you think it is.
