Um. Lemme try to explain that subject line better.
I'm trying to get rid of some excess fat (not aiming for a particularly low BF%, but atm I've got probably 20ish lb. more fat than I need to be healthy.) but it's very important that I not lose too much muscle strength in my arms/shoulders/ back particularly, because I need to lift ~90lb. several times a day in a controlled manner. (The 90lb being my husband, who is disabled and needs physical assistance with things.
After reading the group for a couple of weeks, I'm not sure if I've got the right end of things- it sounds like I'll be on the right track if I cut back on calories a little, but make sure what I am getting is balanced to have enough protein? I can also do some dumbbell exercises (got one of those evil 2.5lb - 10lb six-plastic-coated-dumbbell sets[1]) and have access to an exercise bike. (Although I'm not very fond of using it- it makes the muscles in my thighs cramp up. I *think* it's because of the postion of the seat relative to the pedals, but it's not very adjustable. Or is there some other potential cause I'm missing? The cramping interferes with actually using the bike, because I have to pause and stretch it out every 10 min or so, and it also limits intensity, as more intense riding means faster cramping.)
I'm not particularly concerned with what my actual *weight* does (I've always had a lot of muscle, and I came to terms a few years ago with the idea that I'm never going to be a slim supermodel type.

but I do want the fat to go. (I don't actually know what I weigh at the moment. I'd guess ~180.)
As it's probably important, I'm female, 23, and somewhere around 5'5'. (I typically put muscle on at the drop of a hat. I had calf muscles some people would kill for when I was 11.
I don't feel I particularly need to gain muscle mass. (Could probably do with some more endurance- that's low weight, high rep, right?) Just can't afford to lose a lot of what I have and use.
Last- anyone got any good leg stretches (or a good website/book of them)? My hamstrings are horribly tight, and I feel like I should be doing some regular stretches to try to improve that a bit, just for balance.
