Hi!
I have never been into exercising. When I have worked out at a gym, I've done a couple of weight machines based on what friends have shown me or what the illustrations show. I have no repetoire of exercise plans or activities. The only thing I know is to increase reps at a low weight to tone muscles.
I'm now on the South Beach Diet and have dropped about 30 pounds. I truly feel that exercise is very important to losing this weight, filling up the skin I am loosening with muscle, if possible, and becoming more healthy. However, I am at a loss as to what to do!
I would love help with understanding what I should be doing to build some muscle and tone what I have. I have huge muscles in my legs from years of ballet (stopped when I was 18), and have the weakest arm muscles ever. I can't even do the beginning of a girl pushup. Arm weakness has been a lifelong problem; I was kicked out of gymnastics because my arms were too weak to even doing a handstand against a wall with a coach's help. I would very much like to increase my arm strength.
I am currently working my way up to 30 minutes on the elliptical in the cardio zone (as indicated on the monitor for the machine) three times a week. I am currently at 25 mins and increasing by a minute each workout. I do about 10-12 mins of weights using the nautilus type weight machines. I am currently using the highest weight I can tolerate (=burning sensation in the last four-five reps) and doing 20 reps instead of my usual 15. I just added in some leg exercises. My leg muscles are huge, and I do not really want to increase their size, just tone them.
I have had some problems with my knees in the past two years. I did PT for a while and they found that my inner muscles in the knee area were weak. I did exercises to help that and found that helped a lot, though I still have to be careful.
I would love any suggestions you might have, especially if you can describe exercises for me in language I can understand...I have next to no background in understanding the names of the weight machines and the types of exercises you guys are talking about...I read the "favorite exercises" thread and you guys might as well be speaking Greek!

I just need a lot of help, I guess!

TIA!!!
