i was just wondering what low impact exercises you can do at home? i usually walk three to four times a week for almost two hours, but since summer school started i've barely been able to get out. anyways, i tried doing some weight exercises the other day, for my triceps, and my arms STILL haven't recovered. it was the lowest weight, too, about 4 lbs? could it still tone your muscles if it takes five or six days before you can exercise those muscles again? 'cause i thought you had to do it like every other day, or every three days, something like that. and i feel absolutely awful with all this weight i've put on from meds. i'm not losing anything by just walking, so i need to step it up a bit. and i'm too self concious to go take classes at the gym =[, besides the fact that there's no way i could go to the gym for an hour and a half WITH my summer school classes. any suggestions?
