I just turne 15, but I've been lifting on and off since i turned 14.
My upper body isn't very strong but I just began taking weightlifting as a class in school cause the teacher is a velocity trainer/conditioning coach for my football team.

But over the past two weeks I've been doing benchpress on the shrug machine (put the beach up to it and put hands at the VERY edges) and I started 3 sets of 10 at 85 and could barely finish, but 2 weeks later I'm doing 3 sets of 10 at 115 and finishing pretty easily so I need to go up in weight again. Along with the bench, my butterfly has gone up IMMENSLY from 70 to 110 in about a week and a half. But other than those two exercises I haven't progressed nearly as much in any other excercise =[ can anyone tell me why I'm progressing so fast in that area but not in any other?

And yes I know you don't normally progress that fast but I am in that section but why not others.

It could be the way you train other muscles.

You might be training them with less intensity, or les sets / reps, or the flip side is, you might be overtraining them, causing limited progression.

It could even be how you eat on Chest days, you might be eating extra nutrients, that you don't normally on other days, as a possbility.

Could be genetics, or order you do exercises. For instance if you work out all of your body in one day and do chest first, it will grow the most, because you have more energy to push yourself at the beginning of workout.

Genetics are definitely a possibility too. I had been working out for three months and a buddy of mine caught up to me in two weeks and passed me in 3 weeks on triceps exercises. But I always crushed him in shrugs and legs in a big way. However to this day he is 20-30lbs. ahead of me on any and all tricep-related exercise. Just how it is, and yes he has some serious horseshoes. A different buddy of mine always kicked my arse at bench pressing and I am a lot bigger then him overall, but again, genetics, and the exercises you most enjoy doing.

I would say focus on doing chest exercises after anything else if you combine on that day. My legs respond all to well so I barely even train them because my quads and hams are huge naturally and I do not want my balls crushed every time I go for a run. So I purposefully only do squats and and calf raises on leg day. If did like I used to and and did leg extension and curls in addition I would get way too huge and I am *trying* to be somewhat symmetrical. So you may need to go light on chest as well. Hope that helps.

Post your whole program so I can see the balance of muscle groups and exercises...

obviously if your doing 2 exercises x 3 sets each for a total of 6 sets for chest and only 3 sets for chest, than of course chest will accelerate quickly leaving bacvk behind...

alright here goes (I workout every other day....because its a class at school)

This is in order

I do all of these 3 sets of 10 reps each.

Shrug Benchpress
Leg Press
Pull-downs
Rows
ham curls
quad curls
shoulder press
Butterfly machine
curls on a machine (i jsut do as many as possible at one time)
then as many dips as possible...usually only 4-5 not even...
crunches.

At-home workout:

Pushups...i cant even count the number of sets...
chest iso's
curls
a core workout which consists of a bunch of things

mate can anyone show you some free wt dumbell / barbell exercises?

all you need is a deadlift, a row, a bench press, a pull up/down and lunge variation and you'll have yourself a program

i suggest going to www.exrx.net and looking at the exercise database over there and see if you recognose any of them than get back to me with the one's you do

a deadlift?
i thought dealift was just a bar....

a bar with wts on it is better

today i did deadlift for the first time!
except with dumbbells
40's
i could do way more and i only did 5 reps before my abs starting feeling odd

using db's is fine until your grip can't hold them...

and the ab thing, that's why they're good for abs not to mention the metabolic fat burning effect

yeah i got the strange blisters on my hands

I hate those things, get them all the time, even with weight training gloves, my freind now has a line of odd skin all across the area= BAD!

Click Here - Here's a good article from a gymnast who shows you a good way of removing calluses.

asll callouses are, is a defence mechanism of the body...the skin needs to toughen up so it doesn't cut and / or blister so the body adapts by building callouses...they will be rough at first but they'll smooth out...wearing gloves won't make tyour skin tougher so if you forget them you'll get them again...just tough it out for a couiple of weeks and you'll be set for life
