You already have some good changes. If that is muscle and not just fat, you are already doing very, believe it or not. Be advised, this board is about strength and power, not looking nice with beach muscles.
You went up about 12 pounds in about 6 weeks. That is 2 pounds per week. It is likely that if you did add on muscle, you won't continue to grow that fast for long (unless it is a youthful growing spurt in there too).
What is your routine like? How much are you eating? Why do you need a trainer? Why are you using machines instead of heavy weights? Is your strength improving too or just your appearance of strength?
Thanks for the reply.
Honestly, my performance in the gym in various exercises has really improved. I feel quicker in cardio-esque exercises and last longer than at the start of my sessions last January. I don't look burly or anything, but there's a slight aesthetic improvement, too.
A typical workout entails work with Bosu balls, body holds, squats (no added weight, just where I have one leg hovering, hands on hips, do 20 a side), and things of that nature where it's mostly me versus gravity. Then, I'll move to machines that I don't even know the names of.
Also, we do several amount of non-machine weights, but the weight is easy enough to do 15 reps or so worth. He has not pushed seriously heavy things on me...yet.
I work with a trainer because I want to do my workouts correctly and with no negative infliction on my body. I want to learn gradually and properly so that my body will take a good form now, before college, and be in an improvable position for the rest of my life (until I croak, haha).
Eating has bothered me. My trainer has been good for guiding me and teaching me some fundamentals, but I haven't been given a diet worthy of a skinny kid like me. I know it's important to pack it in many times a day, but I'm not sure how often (I've heard 6 meals is appropriate...) and of what my meals should consist.
Anyway, my workout description is really tough to describe as I have no idea what the exercises are called, I merely know how to do them.
My trainer has told me that he started me with isometric work, branched slowly into weights and machines, and will start building the weight each session. He claims that after several months, physical improvements noticeable to the eye will be more apparent.
Thoughts? Thanks again -- and sorry for posting this in the wrong website. I just stumbled across it and figured 'what the heck.'
